The Senate has confirmed Linda Thomas-Greenfield, a retired career ambassador and former top U.S. diplomat for Africa, as ambassador to the United Nations. The final vote was 78-20, with top Republicans, like Senate Minority Leader Mitch McConnell, voting in favor.

Thomas-Greenfield is the eighth official and the first Black woman confirmed to Biden's Cabinet. The U.S. will assume the presidency of the U.N. Security Council on Monday for the month of March, and Thomas-Greenfield will now be in place for that term, as the U.S. sets the agenda for the U.N.'s highest body.

Her nomination had been held up by Sen. Ted Cruz, R-Texas, who accused Thomas-Greenfield of "moving towards and embracing the Chinese Communist Party" because of a speech she gave at a historically Black college in Georgia that was co-hosted by its Confucius Institute, a Chinese government-funded program that promotes the CCP as part of a language and cultural curriculum. However, Thomas-Greenfield said she regrets accepting the invitation and would not do it again, adding she was "appalled" by the Confucius Institute's treatment of poor Black Georgians.

Biden and first lady Jill Biden will travel to Houston, Texas, on Friday, the White House announced.

The president will visit the state in the aftermath of the catastrophic winter storm that left millions of Texas residents without power and water and killed at least 30 people in the state.

White House press secretary Jen Psaki said last week that the president was considering a trip but was cognizant of the burden and additional resources that a presidential visit can bring.

Biden has already approved a major disaster declaration for the state, opening up federal funds to 77 of the state's 254 counties.

On the second day of Judge Merrick Garland's confirmation hearing, the nominee will not testify but five witnesses will testify virtually about his nomination and credentials. Those witnesses include Wade Henderson, CEO of the Leadership Conference on Civil and Human Rights, Josh Blackman, South College Texas of law professor, Andrea Tucker, a mother in D.C., whose twin children Garland tutors, Ken Starr, former solicitor general and U.S. circuit judge, and Donna Bucella, former director for Executive Office of U.S. attorneys.

Garland emerged virtually unscathed after Monday's hearing, earning praise from senators on both sides of the aisle as he fielded questions on domestic terrorism, racial justice issues and restoring independence to the Justice Department, among other topics.

Republican Sens. Ted Cruz, R-Texas, and Tom Cotton, R-Ark., did express concern over what they described as Garland's unwillingness to pledge that he will not fire special counsel John Durham without proper cause, a commitment they note former attorney general William Barr made during his confirmation hearing about then-special counsel Robert Mueller.

Garland repeatedly emphasized that because he had no knowledge of Durham's investigation he wanted to meet with him first before making a decision but said that because Durham hasn't yet been fired in the new administration he sees no reason to doubt that decision.

Other Republicans, like Sen. Josh Hawley, R-Mo., appeared to grow frustrated over Garland's unwillingness to engage on questions about his views on immigration policy. Garland said he was not completely aware of Biden's immigration policy proposals so declined to wade into the issue.

The first day of hearings for Biden's pick for secretary of health and human services, Xavier Becerra, kicked off with glowing praise from Democrats, who heralded his experience, and criticism from Republicans, who think his resume is a detractor.

Both Sen. Patty Murray, D-Wash., and Sen. Diane Feinstein, D-Calif., who introduced Becerra, highlighted his potential to make history as the first Latino to lead the department and his experience leading massive departments and in policy as a congressman for 24 years. But Sen. Richard Burr, R-N.C., said he is “not sold” Becerra has the “necessary experience or skills to do this job at this moment.”

Becerra, in his opening statement, said he was committed to working in a bipartisan way.

“No one understands your states and communities better than you. We may not always agree, but if I’m fortunate enough to be confirmed, I will always listen to you and keep an open mind, find common cause, and work with you to improve the health and dignity of the American people,” Becerra said.

Becerra laid out his "vision" for the department with three goals: make COVID-19 treatments more accessible, bring down the cost of health care and restore faith in public institutions by putting science first.

Rep. Ted Budd, R-N.C., had a message for Democrats last summer about their proxy voting system set up during the pandemic: it was an "unconstitutional scheme."

"If you use Nancy Pelosi's proxy to skip work, you shouldn't get paid. It's as simple as that," he said in a June 30 Facebook video introducing his new bill withholding member pay for proxy voting.

Budd wasn't alone: A handful of House Republicans previously critical of the proxy vote system submitted letters to have colleagues vote for them, while they were scheduled to appear at CPAC.

Freshman Rep. Madison Cawthorn, R-N.C., tweeted last summer that leaders "show up no matter how uncertain the times are," and that Democrats were "cowards for hiding" and proxy voting.

He was also in Orlando on Friday, telling conservatives activists, "If we sit on the sidelines, we will not have a country to inherit."

"If we do not get involved and say that it is our duty to make sure that our country is responsible, that our country doesn't take away our liberties, then my friends, we will lose this nation," Cawthorn said.

Others Republicans scheduled to appear at CPAC on Friday who also planned to vote by proxy included Reps. Greg Steube of Florida, Virginia Foxx of North Carolina, and Matt Gaetz of Florida, who was one of the first Republicans to support proxy voting.

Curtis Kalin, a spokesman for Budd, said the congressman still opposes proxy voting, and will donate his salary for the days he used the system to a restaurant relief fund, given his bill last year, "The No Pay for Proxy Voting Act."

The Republicans who attended CPAC aren't alone in their questionable use of the proxy voting system -- established by House Speaker Nancy Pelosi, D-Calif., last year to cut down member travel to Washington during the COVID-19 pandemic.

Last year, Rep. Greg Stanton, D-Ariz., was caught voting during a Transportation Committee hearing from a boat during a family trip to Utah. Stanton later apologized and said he "messed up."
