President Obama, in London to meet with the British prime minister, joked that he "warmed up" for those meetings this morning playing Prince's "Purple Rain" and "Delirious."

Obama has long been a fan of the musician, who died yesterday at the age of 57.

The president said he is staying at the U.S. ambassador's residence and "it so happens our ambassador has a turntable, and so this morning we played 'Purple Rain' and 'Delirious' just to get warmed up before we left the house for important bilateral meetings like this."

Following widespread irregularities at polls in Brooklyn Tuesday, New York City officials are calling for major reforms at the Board of Elections.

The problem was first identified in a an analysis of state voter enrollment statistics by WNYC's Brigid Bergin. The Board of Elections then confirmed that more than 120,000 voters have been dropped from the rolls in Brooklyn alone since November.

The Trump campaign will open a Washington, D.C., office next week, part of a larger move the campaign is making toward becoming a more traditional political operation.

The plans were first announced last week, but the office opening will come following Donald Trump's bruising, 13-point loss to Ted Cruz in Wisconsin on Tuesday.

Senate Majority Leader Mitch McConnell vowed again Wednesday to block President Obama's Supreme Court nomination, saying the American people should have a "voice" in the process.

Hillary Clinton had a big night Tuesday, cheered by an exultant crowd in Palm Beach, Fla., as she won four states and led in a fifth. But some people on social media criticized Clinton's tone during her speech.

It started with several tweets from male television personalities.

MSNBC's Joe Scarborough told her: "Smile. You just had a big night."

Just before that, he had tweeted: "What a massive night for @HillaryClinton."

Donald Trump's campaign has spent an unusual amount of time this week answering questions about violent incidents.

The latest involves an allegation by reporter Michelle Fields of conservative site Breitbart that she was assaulted by someone who was ID'd by another reporter as Trump's campaign manager.

Here's what we know:

What Fields reported

President Obama said Thursday that the Republican Party is responsible for Donald Trump's rise, for "over a course of time, creating an environment where somebody like Donald Trump can thrive." Obama refuted the argument that Trump's surge is a reaction to his presidency.

"He's just doing more of what has been done for the last 7 1/2 years. And, in fact, in terms of his positions on a whole range of issues, they're not very different from any of the other candidates," Obama said in response to a question during a news conference with Canadian Prime Minister Justin Trudeau.

Bernie Sanders was the story of Tuesday night as he beat Hillary Clinton in Michigan's Democratic presidential primary. It wasn't a walloping — he won by less than 2 points — but still a big coup considering Clinton led in most polls by double digits before the race.

Michigan is Sanders' ninth state win, though Clinton still leads in delegates overall.

That means Sanders is only partway up a steep hill to the nomination.

Businesswoman Carly Fiorina, who ended her own presidential bid last month, has endorsed Texas Sen. Ted Cruz.

Appearing at a Cruz rally in Miami on Wednesday morning, Fiorina said she voted for Cruz in Virginia's recent primary, and praised his record in challenging Washington's status quo.

Calling Cruz a "real constitutional conservative," she said "he is a fearless fighter and reformer, and he didn't care much whether he got invited to the cocktail parties in Washington, D.C." Fiorina said.

Former three-term mayor of New York City Michael Bloomberg said Monday he will not run for president, after months of speculation that he would jump in as in independent during a campaign in which it seems anything could happen.

Abraham Lincoln trended on Twitter this week. Wait, what? Honest Abe proved what's become a hipster creed: Everything old becomes new again.

Friday would have been the 16th president's 207th birthday — as good a time as any to bring him back with a party hat on him (like the House Republicans did):

There were also memes of Lincoln holding pizzas, stereos and cellphones. But the memes also quickly became about the presidential candidates, with the hashtag #ThingsLincolnDidntSay. Talk about putting words in someone's mouth.

We all know live election coverage is hard — you have to cram a lot of quickly changing information into not a lot of time, and sometimes you forget to eat dinner. MSNBC's Chris Hayes must have been hungry, because here's what he said after Bernie Sanders was announced a winner:

This week, NPR asked voters around the country how they are feeling about this election, and why so many tell us they are anxious or angry.

President Obama and Vice President Biden "have tried to be fair and even-handed" in the primary process, Sen. Bernie Sanders said Wednesday following a meeting with the president at the White House.

Calling the meeting "constructive and productive," Sanders cautiously praised the Obama administration's economic work, saying there is still work to be done. The two also talked talked about foreign and domestic policy and "a little bit of politics," according to Sanders, who spoke to reporters after the meeting.

Several GOP presidential candidates are starting to lay out their closing messages in a new round of campaign ads airing in Iowa and New Hampshire this week. The ads come ahead of the early February primaries in those states.

They strike a dark and fearful tone, with footage and news headlines highlighting the recent terror attacks in San Bernardino, Calif., and Paris.

It all started with a question about food labeling at the Iowa Agriculture Summit earlier this year and Jeb Bush's not-so-humble brag:

"When I go to Publix in Coral Gables after church to go prepare for Sunday Funday in my house ... I'll probably make a really good guacamole and I want to know where that avocado is from and I want to know where the onions are from and the cilantro and all the secret stuff I put in it."

Stressing that his administration has "been at this for a long time," President Obama launched a forceful defense of his strategy against ISIS in a year-end interview with NPR. He makes "no apologies," he said, for wanting to target terror groups "appropriately and in a way that is consistent with American values."

Speaking with Steve Inskeep, host of Morning Edition, Obama also urged Americans to "keep things in perspective" when it comes to ISIS, though he says he understands "why people are worried."

Weighing in at 17 1/2 pounds, 4-month-old giant panda cub Bei Bei made his media debut Wednesday at the Smithsonian National Zoo. Keepers say the cub, born in August, is developmentally on track and ahead of his older sister Bao Bao in some milestones. The cub will make his public debut on Jan. 16.

"He's actually walking a lot sooner than his older sister did," said panda keeper Juan Rodriguez. "He's about 4 or so pounds heavier than his sister was at this same age, so he's definitely a much larger bear and developing a lot faster than his sister did."

Four low-polling presidential candidates — Mike Huckabee, Rick Santorum, George Pataki and Lindsey Graham — met Tuesday night in Las Vegas knowing they needed to do something big to stand out.

That didn't quite happen. But Graham, a retired Air Force colonel who said he has now been to Iraq 36 times, found new energy in this debate, which focused almost entirely on fighting terrorism and ISIS. Graham said he would try to make friends throughout the world to fight ISIS and that he's "been working for a decade to figure out how to win this war," he said.

Fourteen Republican candidates are speaking Thursday at a forum hosted by the Republican Jewish Coalition in Washington, D.C. Comments made by front-runner Donald Trump are already garnering criticism on social media.

Trump spoke about Wednesday's shooting in San Bernardino, Calif., saying it "probably was related" to "radical Islamic terrorism." He criticized Obama for not using the term.

It starts with seemingly benign questions: Who are you voting for? Did you see that exposé about candidate X on Facebook? Before long, somebody is storming off to the basement or slamming the mashed potatoes on the table. And playing Adele's new song "Hello" won't make every family instantly get along (a la SNL's Thanksgiving Miracle).

Bernie Sanders laid out his brand of Democratic socialism Thursday, explaining how it informs his views on higher education, poverty, health care, the minimum wage and more.

In response to last week's terrorist attacks in Paris, House Republicans have formed a task force charged with finding a legislative response to calm fears about Syrian refugees coming into the U.S.

Speaking on Capitol Hill on Tuesday, House Speaker Paul Ryan called the attacks "pure evil."

"It's clear that this was an act of war and that the world needs American leadership," he said.

Three Democratic candidates for president debated Saturday in Des Moines. NPR's politics team held a live chat during the debate at #nprdebate on Twitter. The chat has now ended but you can see an archived version below.

The Republican National Committee says it will suspend a debate partnership with NBC News, citing "inaccurate or downright offensive" questions during Wednesday night's debate on CNBC.

"We simply cannot continue with NBC without full consultation with our campaigns," RNC Chairman Reince Priebus wrote in a letter to NBC Chairman Andrew Lack.

Paul Ryan has been elected speaker of the House of Representatives, receiving 236 votes.

Ryan faced the full House vote Thursday after getting approval Wednesday from the House Republican conference. He faced token opposition from fellow conservative Daniel Webster and Democrat Nancy Pelosi.

Speaker John Boehner gave farewell remarks on the House floor Thursday, picking up a box of tissues as he prepared to speak, a nod to his tendency to cry in emotional moments.

Officially announcing his intent to resign as speaker and the representative from Ohio, Boehner said he leaves "with no regrets, no burdens. If anything, I leave the way I started, just a regular guy, humbled by the chance to do a big job."

He spoke for 10 minutes about his life and rise in government, accomplishments in Congress and the role of the body.

The Republican presidential candidates gathered again Wednesday — this time in Boulder, Colo. for their third debate.

House Republicans have voted to elect Wisconsin Republican Paul Ryan as the party's nominee to serve as the next speaker of the House.

"This begins a new day in the House of Representatives," Ryan said, speaking briefly to reporters after Wednesday's vote. "Tomorrow, we are turning the page. We are not going to have a House that looked like it looked the last few years. ... Our party has lost its vision and we're going to replace it with a vision."
