President Donald Trump and first daughter Ivanka Trump condemned anti-semitism on Tuesday.

"The anti-Semitic threats targeting our Jewish community -- and community centers -- are horrible," the president said. "And are painful. And a very sad reminder of the work that still must be done to root out hate and prejudice and evil."

Earlier Tuesday, Trump told MSNBC during a tour of the National Museum of African American History: "Anti-semitism is horrible. And, it's gonna stop and it has to stop."

The president appears to have been responding to nationwide bomb threats against Jewish community centers and an incident on Monday of anti-Semitic vandalism in University City, Missouri.

In Missouri, more than 100 tombstones were either "toppled or damaged" in a historic Jewish cemetery, according to local media. University City is 10 miles from St. Louis.

Ivanka Trump and her husband White House adviser Jared Kushner practice Orthodox Judaism. She spoke out on Monday night.

"America is a nation built on the principle of religious tolerance. We must protect our houses of worship & religious centers. #JCC" she tweeted. "JCC" stands for Jewish community center.

Earlier Tuesday, Trump's former Democratic rival for the presidency, Hillary Clinton, had urged the White House to speak out.
