Cuellar and Graham’s letter is the latest in a series of criticisms against the Biden administration’s border security response.

WASHINGTON – Alabama Sen. Doug Jones and federal appeals court judge Merrick Garland are emerging as the leading contenders to be nominated as President-elect Joe Biden’s attorney general, three people familiar with the matter told The Associated Press. Biden's thinking was described by people with knowledge of the presidential transition's internal thinking who were not authorized to speak publicly. Jones, who is white, has had a long-standing personal relationship with Biden dating back to Biden’s first presidential campaign in 1988. Jones would not comment Tuesday on the possibility of a nomination as attorney general. The Biden team has also been considering a number of other potential candidates for the post, including former Justice Department official Lisa Monaco.

Biden countered the concerns by arguing that Austin knows that a Pentagon chief's duties are different from those of a military officer. But the requirement for a congressional waiver makes getting him installed as Pentagon chief more complicated than usual. Austin retired in 2016 after 41 years in the Army and has never held a political position. Some prominent Democrats opposed the Mattis waiver, and among those who voted for it, Sen. Jack Reed of Rhode Island expressed doubts. Biden has known Austin at least since the general's years leading U.S. and coalition troops in Iraq while Biden was vice president.

WASHINGTON – President-elect Joe Biden will nominate retired four-star Army general Lloyd J. Austin to be secretary of defense, according to four people familiar with the decision. Biden selected Austin over the longtime front-runner candidate, Michele Flournoy, a former senior Pentagon official and Biden supporter who would have been the first woman to serve as defense secretary. Biden also had considered Jeh Johnson, a former Pentagon general counsel and former secretary of homeland defense. Like Mattis, Austin would need to obtain a congressional waiver to serve as defense secretary. When Austin retired in 2016, Obama praised his “character and competence,” as well as his judgment and leadership.

WASHINGTON – President-elect Joe Biden is facing escalating pressure from competing factions within his own party as he finalizes his choice for secretary of defense. And facing massive governing challenges once he takes office on Jan. 20, Biden can perhaps least afford to lose the backing of the Democratic Party’s fiery progressive base. Nearly 100 House Democrats belong to the Progressive Caucus, which may wield significant influence over Biden's policy agenda as Democrats cling to their narrowest House majority in a century. Flournoy, meanwhile, had been seen as the leading candidate for defense secretary under a Democratic president since Hillary Clinton’s failed 2016 campaign. Biden has promised both to fight for big, bold policy changes and to compromise with Republicans.

Flournoy, a politically moderate Pentagon veteran, is regarded by U.S. officials and political insiders as a top choice for President-elect Joe Bide to choose to head the Pentagon. Michele Flournoy, a politically moderate Pentagon veteran, is regarded by U.S. officials and political insiders as a top choice for the position. If confirmed, Flournoy would face a future that is expected to involve shrinking Pentagon budgets and potential military involvement in the distribution of a coronavirus vaccine. She has been outspoken on American foreign and defense policy, particularly over the past year. The Defense Department is one of three Cabinet agencies — the others being Treasury and Veterans Affairs — that have never been led by a woman.
