Biden fractures foot after fall, will likely be in walking boot 'for several weeks'

Biden’s nominee for ambassador to the United Nations, Linda Thomas-Greenfield, spoke out about her hope for the nation and had a special message for fellow diplomats. 

“In the years that I've worked in government, I'm always struck by how only in America would we be where we are today, where life can be hard and cruel, but there's hope in the struggle, there's promise in our dreams,” she said during remarks Tuesday. “Where you learn to believe in yourself, and that anything is possible.” 

She also addressed diplomats and American public servants around the world, saying, “I want to say to you, America is back, multilateralism is back.” 

Finally, she paid tribute to her mentor, diplomat Ed Perkins, who passed away last week. 

“He told me constantly, ‘Linda, don't undersell yourself.’ And he would always do everything possible to lift me up. He passed away last week, but I know he's here with us today,” she said.

Avril Haines, Biden’s nominee for director of national intelligence, would be the first woman to serve in her role. 

In remarks, she pledged to represent the “patriots” that comprise the intelligence community and to speak truth to power.

“Mr. President-elect, you know that I have never shied away from speaking truth to power, and that will be my charge as director of national intelligence,” Haines said. “I've worked for you for a long time and I accept this nomination knowing that you would never want me to do otherwise, and that you value the perspective of the intelligence community, and that you will do so even when what I have to say may be inconvenient or difficult, and I assure you there will be those times.”

The first Latino and immigrant nominated to lead the Department of Homeland Security, Alejandro Mayorkas spoke about immigrating to the United States during remarks Tuesday. 

"For 12 years, I had the privilege to stand in a federal courtroom and announce 'Alejandro Mayorkas on behalf of the United States of America,'" he said. "The words, 'on behalf of the United States of America,' meant everything to me and to my parents, whom I think of today and every day." 

"My father and mother brought me to this country to escape Communism. They cherished our democracy and were intensely proud to become United States citizens, as was I," he added. "I have carried that pride throughout my nearly 20 years of government service and throughout my life." 

Mayorkas pledged to work "day and night in the service of our nation" as leader of the DHS.
