The White House vowed on Sunday to fight the news media "tooth and nail" over what it sees as unfair attacks, with a top adviser saying the Trump administration had presented "alternative facts" to counter low inauguration crowd estimates.
On his first full day as president, Trump said he had a "running war" with the media and accused journalists of underestimating the number of people who turned out Friday for his swearing-in.
White House officials made clear no truce was on the horizon on Sunday in television interviews that set a harsher tone in the traditionally adversarial relationship between the White House and the press corps.
