U..S. President Donald Trump assailed a woman TV news host in highly personal terms on Thursday, calling her "crazy" and alleging she had been bleeding at one point from a facelift, in a Twitter attack that drew strong criticism including from fellow Republicans.

Trump, who often decries what he calls "fake news" in the American media and who this week attacked CNN, the New York Times and the Washington Post, took fierce aim on Thursday at the hosts of the MSNBC program "Morning Joe," Joe Scarborough and Mika Brzezinski.

The Republican president called Brzezinski, a journalist and daughter of former White House national security advisor Zbigniew Brzezinski, "low I.Q. Crazy Mika" and said she was "bleeding badly from a face-lift" when she visited one of his properties around New Year's Eve.
