President-elect Donald Trump's designees for national intelligence, defense secretary, and the Federal Bureau of Investigation faced tough questioning from senators on Monday.Former Congresswoman Tulsi Gabbard is Trump's pick for the director of national intelligence. The Democrat-turned-Republican is a lieutenant colonel in the U.S. Army Reserve and a decorated combat veteran.In 2022, Gabbard said the Ukraine war could have been avoided, "if Biden Admin/NATO had simply acknowledged Russia's legitimate security concerns."Gabbard also faced scrutiny for a secret 2017 meeting with now-exiled Syrian dictator Bashar al-Assad."It does call into question whether a person who held those outrageous views could suddenly be sitting next to the president of the United States and have the last word as he makes decisions about how the U.S. should respond to a situation like this," said Rep. Dan Kildee, a Michigan Democrat.Trump tapped loyalist Kash Patel to lead the FBI. Patel pledged to radically transform the law enforcement agency, including shutting down the D.C. headquarters."I'd take the 7,000 employees that work in that building and send them across America to chase down criminals, go be cops," said Patel during an interview on the Shawn Ryan Show.Democrats say Patel could weaponize the agency. Patel previously talked about going after his and Trump’s perceived enemies."They have literally published an enemies list," said Rep. Brendan Boyle, a Pennsylvania Democrat.Republicans dismissed Patel's rhetoric after meeting with him on Monday."I interpret that as hyperbole," said Sen. John Cornyn, a Texas Republican.Trump, on Meet the Press Sunday, said he won’t direct the FBI to investigate his political enemies, but he believes Patel will do "what he thinks is right."
