Rep. Marjorie Taylor Greene (R-Ga.) doubled down on her criticism of President Trump in an interview on CBS's "60 Minutes" on Sunday, less than a month after the longtime Trump ally announced she would resign from Congress amid her public feud with the president. In the interview, Greene stood by the defiant stances she's taken against the president in recent months and said some of her GOP colleagues stay mum because they're "terrified" of publicly breaking with the president, as the Georgia congresswoman has.
