US President Donald Trump renewed his criticism of London Mayor Sadiq Khan Monday, in the second such condemnation in the 48 hours since a terror attack in the British capital. 

Trump accused Khan of offering a "pathetic excuse" for comments that Trump earlier misconstrued about policing in response to Saturday's attack, which left seven people dead.

Khan had told Londoners there was "no reason to be alarmed" about an increased police presence in the coming days.

Trump leapt on the London attacks as evidence of the need for hardline security measures in the United States, including a "ban" on travelers from Muslim countries.
