President Donald Trump is getting pushback from political leaders in the United Kingdom after he used terrorist attacks to lash out at London Mayor Sadiq Khan.

Following the recent terrorist attacks that killed seven in London, Trump repeatedly and incorrectly blasted Khan by suggesting that the mayor had said that there was “no reason to be alarmed” by the terrorist attacks. In fact, Khan had been informing citizens that they should not be alarmed by the sight of armed policeman on London streets.

Trump also used the tragedy to push a ban on some Muslim travelers.

In a statement on Monday, Liberal Democrat leader Tim Farron called for British Prime Minister Theresa May to rescind Trump’s invitation to the country.

“Trump is an embarrassment to America,” Farron said. “In the wake of the recent terrorist attack, two of which killed people on the streets of London, Donald Trump decides to use his time in the Oval Office to attack the Mayor of London on Twitter.”

“Theresa May absolutely must withdraw the state visit,” he added. “This is a man insulting our national values at a time of introspection and mourning.”

“We need a special relationship not a supine relationship,” the statement concluded.
