President Donald Trump speaks during a rally in Las Vegas, Nevada, U.S., on Thursday, Sept. 20, 2018.



Facebook on Monday said it would no longer allow President Donald Trump's re-election campaign to run advertisements urging Americans to vote for Republicans to stop thousands of immigrants from crossing the U.S. border, saying the ad violated company policy.

"This ad violates Facebook's advertising policy against sensational content so has been rejected," a company spokeswoman said in a statement on Monday. "While the video is allowed to be posted on Facebook, it cannot receive paid distribution."

The 30-second advertisement, which CNN and others have called "racist," warns Americans of "an invasion" of 7,000 immigrants headed to the U.S.

"Stop the caravan. Vote Republican. I'm Donald Trump, and I approve this message," the advertisement says.
