The exchange began when the network’s chief White House correspondent asked the longtime confidant and adviser to Donald Trump if the president intends to “tell the truth” during a prime-time address Tuesday night from the Oval Office.

Conway then shot back a question about whether Acosta intends to tell the truth when he goes back on air, prompting him to opine that she has an “alternative facts problem.”…

“You’re such a smartass most of the time,” Conway said in front of a small throng of journalists — including television cameras — after she did a television hit on the White House’s North Lawn to preview Trump’s first Oval Office address.

As they traded sick burn for sick burn, Conway charged Acosta with wanting the exchange to “go viral,” adding of the other media members gathered around them: “A lot of these people don’t like you.”
