President Trump’s oldest son blasted the mayor of London on Wednesday — hours after a terrorist killed three people outside Parliament — twisting several comments the mayor made six months ago that such attacks should be expected.

Terror attacks are “part and parcel of living in a big city,” Mayor Sadiq Khan said to the Evening Standard in September, following a bomb explosion in Chelsea in Manhattan that injured 29 people. “It is a reality I’m afraid that London, New York, other major cities around the world have got to be prepared for these sorts of things. That means being vigilant, having a police force that is in touch with communities, it means the security services being ready, but it also means exchanging ideas and best practice,” said Khan, who has called President Trump’s take on Muslims “ignorant.”

“You have to be kidding me?!: Terror attacks are part of living in big city, says London Mayor Sadiq Khan,” Donald Trump Jr. tweeted and linked to Khan’s earlier comments.
