A Russian pop star may be the next lead in Special Counsel Robert Mueller's investigation.

Mueller has requested an interview with Emin Agalarov, the Russian singer who helped organize the June 2016 meeting between Trump affiliates and Kremlin-linked lawyer Natalia Veselnitskaya, NBC News has learned from Agalarov's lawyer.

Veselnitskaya possessed incriminating information on Hillary Clinton, Agalarov's father Aras wrote in an email to publicist Rob Goldstone, who passed the information on to Donald Trump Jr. President Trump's eldest son infamously responded with, "If it's what you say, I love it." Trump Jr., the president's son-in-law Jared Kushner, then-Trump campaign chair Paul Manafort, and Veselnitskaya met in Trump Tower days later. Veselnitskaya said she was there to lobby against U.S. sanctions, and Trump Jr. later said he never got information on Clinton.

Aras Agalarov sent the email to Goldstone, but Veselnitskaya told NBC News last year that son Emin played a key role in organizing the meeting. President Trump appeared in an Emin Agalarov music video in 2013, and the singer released a 2018 video parodying the Mueller investigation. The pop star's lawyer did not tell NBC News if Mueller wants to speak with Aras Agalarov, who's tied to Russian President Vladimir Putin. Kathryn Krawczyk

If you work for the White House and have any travel scheduled, you better hope your passport says "Melania Trump."

On Thursday afternoon, President Trump put the kibosh on an overseas trip House Speaker Nancy Pelosi (D-Calif.) planned on taking with a congressional delegation. Just a few hours later, White House press secretary Sarah Huckabee Sanders released a statement saying that another trip was off, as Trump canceled the U.S. delegation's jaunt to Davos, Switzerland, for the World Economic Forum.

Sanders said the trip was canceled "out of consideration for the 800,000 great American workers not receiving pay and to ensure his team can assist as needed." Trump tweeted earlier this month that he was no longer going to take his "very important trip" to Davos, and the delegation would have been led by Treasury Secretary Steven Mnuchin, with Secretary of State Mike Pompeo, Commerce Secretary Wilbur Ross, U.S. Trade Representative Robert Lighthizer, and Chris Liddell, deputy chief of staff for policy coordination, attending.

So far, there is just one person in the White House who hasn't had her travel plans canceled, and that's first lady Melania Trump. She boarded Air Force One on Thursday afternoon and flew down to Palm Beach, Florida, home to Trump's beloved club Mar-a-Lago. Maybe if everyone back in Washington is lucky, she'll send them a postcard. Catherine Garcia

Rep. Tulsi Gabbard (D-Hawaii) apologized on Thursday for anti-LGBTQ comments she made while working for her father Mike Gabbard's organization, The Alliance for Traditional Marriage.

The Alliance for Traditional Marriage pushed for an amendment to Hawaii's state constitution banning same-sex marriage and advocated against pro-gay rights lawmakers, Politico reports. In the 1990s, Mike Gabbard said homosexuality is "not normal, not healthy, morally and scripturally wrong," and while running for Hawaii state legislature in 2002, Gabbard defended her father and her work for his group. Gabbard apologized for her comments in 2012, but since announcing last week that she will run for president in 2020, her past remarks are once again under scrutiny.

On Twitter, Gabbard said that she grew up in a socially conservative home and in her past, she "said and believed things that were wrong, and worse, hurtful to people in the LGBTQ+ community and their loved ones. I'm deeply sorry for having said and believed them." Now, she is a member of the House LGBT Equality Congress, and knows that "LGBTQ+ people still struggle, are still facing discrimination, are still facing abuse and still fear that their hard-won rights are going to be taken away by people who hold values like I used to. I regret the role I played in causing such pain, and I remain committed to fighting for LGBTQ+ equality." Catherine Garcia

President Trump may want House Speaker Nancy Pelosi (D-Calif.) to fly commercial, but first lady Melania Trump certainly doesn't have to.

After the speaker suggested she might rescind her invitation for Trump to deliver the State of the Union address, the president promptly shelved what he called her "public relations" trip to "Brussels, Egypt, and Afghanistan" scheduled for Thursday afternoon. Members of Congress usually use Air Force One for these trips.

Air Force One still took off that afternoon, but it didn't head overseas, Politico's Jake Sherman and aircraft-watching CivMilAir tweeted. It was using code that typically means the first lady is onboard, and it was headed for Mar-a-Lago's city of Palm Beach, Florida.

Pelosi hadn't announced her Congressional Delegation, or codel, trip before Trump issued the letter, in which he encouraged her to either "negotiat[e] with him" about the ongoing government shutdown or take a commercial flight to Afghanistan. Pelosi responded by saying her codel was stopping in Brussels to meet with "top NATO commanders, U.S. military leaders and key allies." She was also headed to Afghanistan to meet with troops and "obtain critical national security and intelligence briefings," adding that a stop in Egypt was never part of the plan.

As NPR's Kelsey Snell pointed out, codels are usually not publicly announced for security reasons, making Trump's "flying commercial" suggestion useless. Kathryn Krawczyk

Everything experts warned would happen after California's wildfires subsided? It's happening.

Massive snow, rain, and wind storms have rocked the state from top to bottom this week, leaving at least six dead, The Associated Press reports. And with thousands of acres of trees gone after October's massive wildfires, mudslides and flash floods were quick to follow.

Heavy rain and snow started falling Tuesday in "a significant part of California" thanks to a "storm rolling in from the Pacific Ocean," an Accuweather meteorologist told USA Today earlier this week. Conditions have remained harsh ever since, bringing a winter storm warning to southern California and blizzards to the tops of the Sierra Nevadas through Thursday. Four people died in storm-related car accidents, one died when a tree fell on a homeless encampment in Oakland, and another died while fleeing a falling tree, per AP.

While rain helped douse the Camp Fire in northern California in November, it also increased the risk of deadly floods and mudslides because no vegetation remained to absorb the runoff, experts said. Those risks became a reality this week as up to 7 inches of rain were expected through Friday in the ravaged town of Paradise, with the National Weather Service issuing a flash flood watch in the town's Butte County.

The storms came a week after President Trump said he would cut off federal disaster funding to the state because "with proper forest management," the wildfires "would never happen." Thousands of families are still rebuilding after last year's fires, and the government shutdown could delay recovery efforts even further. Kathryn Krawczyk

Pennsylvania's 12th District just got a new representative. And now it needs another one.

Less than three weeks after he was sworn into office, Rep. Tom Marino (R-Pa.) has announced he's stepping down. Marino is going to "take a position in the private sector" after "spending over two decades serving the public," he said in a Thursday statement. He didn't exactly say what that private sector job is, but broke down three of the eight bills he's introduced that became laws in the press release.

Before easily winning his seat last fall, Marino served as a four-term senator for Pennsylvania's 10th District, which was redistricted into the 12th. President Trump nominated him to be the federal "drug czar" in 2017, but he withdrew his name after a report showed he pushed for a pharmaceutical industry-backed bill that stripped the Drug Enforcement Administration of its biggest tool to fight prescription opioids entering the black market. Democratic Gov. Tom Wolf will now have to schedule a special election for the heavily Republican district, per Politico.

Marino's decision is especially ironic seeing as just last week, he introduced an amendment to the constitution that would let representatives serve 4-year terms. In a statement accompanying the proposed amendment, Marino said he'd "serve 12 years and then let new blood and ideas take the reins," but apparently he let go a few years early. Kathryn Krawczyk

All Keanu Reeves' John Wick ever wanted was to hang out with his puppy, Daisy. But after losing his dog — not to mention his wife, house, car, and pretty much everything else to hordes of gun, knife, and grenade-launcher-toting gangsters in the first two John Wick films, it doesn't seem like things are getting any easier for the perpetually-pulled-out-of-retirement-by-a-righteous-code-of-honor hitman, if the first trailer for John Wick 3: Parabellum, released Thursday, is any indication. From the looks of things, the series' world-building maximalism, rain-splashed neon colors, and, of course, femur-snapping violence are entirely present in the franchise's second sequel — with a swaggering Halle Berry now added for good measure.

John Wick 3: Parabellum opens on May 17, and will look to build on the surprising box office success of John Wick: Chapter 2, which earned $171.5 million — more than double that of the original, which pulled in $88.8 million. Reeves could certainly use a hit, with his much-derided new sci-fi thriller, Replicas, having earned a paltry $2.9 million, according to Box Office Mojo — or roughly $11 million less than the bounty placed on our hero's head in John Wick 3: Parabellum.Jacob Lambert
