Cheney took to Twitter earlier Monday to slam Tlaib, one of the first Muslim woman elected to Congress, for making allegedly false remarks critical of Israel.

“Here’s @RepRashida direct quote, ‘There’s a calming feeling I always tell folks when I think of the Holocaust.’ And her ‘history’ of what happened after is a fantasy based on lies spread to delegitimize the state of Israel,” Cheney tweeted on Monday morning.

“Give it up, we all know you never met a Muslim you didn’t want to vilify!,” Omar responded later in the day. “Your deep seeded hate and Islamophobia might be a tool to rally your base, but won’t get rid your colleagues. You just have to deal.”
