Avalon - Some of former President Donald Trump's fellow Republicans on Sunday lashed out at him for saying he would not want to protect NATO members from a future attack by Russia if those countries' contributions to the defense alliance were lagging."This is why I've been saying for a long time that he's unfit to be president of the United States," former Republican presidential candidate Chris Christie said in an interview with NBC's "Meet the Press" program.
