Opponents of special counsel Robert Mueller ramped up their attacks over the weekend with a new claim that he improperly collected thousands of emails from President Trump's transition team and is using them as an illegitimate basis for much of his investigation.

Mueller's office said his team has obtained all the evidence it's using in its investigation properly. And Deputy Attorney General Rod Rosenstein, who appointed him, told Congress last week that he monitors Mueller's operation closely and has seen nothing improper.

A viral video making the rounds Friday has one of President Trump's judicial nominees in an uncomfortable spotlight.

Matthew Petersen has been nominated for a judgeship on the U.S. District Court for the District of Columbia, one of the nation's most important federal courts. Petersen is now a member of the Federal Election Commission.

But his trouble began during Wednesday's confirmation hearing before the Senate Judiciary Committee when, among a panel of five nominees, he alone told Sen. John Kennedy, R-La., that he had never tried a case in court.

President Trump, minutes before heading to speak at the FBI's National Academy, lashed out at the bureau, saying, "It's a shame what's happened with the FBI" and claiming there are "a lot of very angry people that are seeing it."

The New Year will bring a new test for President Trump and the United States' relationship with Russia.

Five years ago, President Obama signed a bill imposing sanctions on a group of powerful people there charged with involvement in the death of a Russian lawyer who uncovered a $230 million tax fraud scheme — and then died in government custody. The sanctions infuriated Russian President Vladimir Putin.

Trump SoHo is a high rise in lower Manhattan, part hotel, part condos; it's 46 stories tall, all slick grey glass. Conflicts, from zoning battles to accusations of fraud, have followed the project since it was announced during a 2006 episode of The Apprentice.

According to reports by Bloomberg News, Trump SoHo has attracted the interest of Department of Justice special counsel Robert Mueller, who is investigating possible ties between Trump's 2016 presidential campaign and Russian officials.

President Trump said thank you Wednesday evening to Omarosa Manigault Newman, the former Apprentice and Celebrity Apprentice contestant turned White House aide, who is stepping down from her post.

"I wish you continued success," Trump posted on Twitter.

In deep-red Texas, Republicans will have to fight for every seat in Congress during next year's midterm elections. For the first time in 25 years, Democrats are running in all of Texas' 36 congressional districts, according to documents filed with the Texas Secretary of State's office.

Those filings set a record for the number of Democratic challengers in an era of Republican dominance, says Mark Jones, political science fellow at Rice University's Baker Institute. It is a departure from 2016, he says, when eight Republican-held congressional seats went uncontested by Democrats.

When Deputy Attorney General Rod Rosenstein faces questions Wednesday on Capitol Hill about the investigation into Russia's election interference, he is certain to be asked about unflattering text messages exchanged by FBI agents about then-candidate Donald Trump.

In the text messages, seen by NPR's Carrie Johnson, between agents Peter Strzok and Lisa Page, Trump is referred to several times as an "idiot."

With a single 8 a.m. tweet, a classic Trumpian feud has erupted between the president of the United States and the junior senator from his home state, a high-profile female Democrat who called his tweet "a sexist smear."

Sen. Kirsten Gillibrand, D-N.Y., was attending a bipartisan Senate prayer meeting Tuesday morning when she got a phone call. President Trump had tweeted about her.

This appears to have been a response to Gillibrand's call on Monday for Trump to resign.

Nikki Haley, the U.S. ambassador to the U.N., said on Sunday that women who have accused President Trump of sexual harassment and assault "should be heard."

More than a dozen women came forward during the 2016 campaign with allegations of unwanted touching or kissing or other forms of sexual harassment.

Haley addressed the allegations on CBS's Face the Nation, after discussing North Korea's missile tests and the plan to move the U.S. Embassy in Israel to Jerusalem.
