The hosts of "Fox & Friends Weekend" blasted a CNN host for posting an expletive-laden tweet directed at President Trump, moments after the London terror attack unfolded.
Reza Aslan, an Iranian-American religious studies expert who hosts a Sunday program on the network, called Trump a "piece of [expletive]" for saying America must get "tough" on terror.
"We need to be smart, vigilant and tough. We need the courts to give us back our rights. We need the Travel Ban as an extra level of safety," Trump tweeted.
Aslan responded by calling Trump the obscenity, as well as an "embarrassment to America and a stain on the presidency."
The tweet has been altered above to censor the expletive.
Previously, Trump retweeted an alert from Matt Drudge's "Drudge Report" which said there had been a terror attack on the London Bridge.
