Former CIA Director John Brennan said Wednesday that it’s important for President Trump to change his rhetoric, especially in light of the recent bombs sent to him and other prominent Democrats.

"Unfortunately, I think Donald Trump too often has helped to incite some of these feelings of anger, if not violence,” Brennan said Wednesday during a Q&A at the University of Texas at Austin, after several more suspicious packages were discovered.

A package was sent to CNN’s offices in New York addressed to Brennan, who appears on NBC and MSNBC as a contributor. The CNN offices were evacuated Wednesday morning.

Brennan said that he felt all of the former presidents he served under while he was CIA director were unifiers who brought citizens of the country together, especially in times of trouble.

"Unfortunately I think Donald Trump has not helped to encourage the type of civil discourse and public engagement, and his rhetoric too frequently, I think, fuels these feelings and sentiments that now are bleeding over into potentially acts of violence," Brennan said.

Brennan said that he hopes the multiple bomb threats and interceptions of suspicious packages this week will encourage Trump to stop his “counterproductive,” “un-American” rhetoric.

“Follow up on those words with actions and with future comments,” Brennan said. “I’m hoping, that maybe, this is a turning point.”

Billionaire Democratic megadonor George Soros was sent an explosive package Monday, and on Tuesday, a potentially explosive device was sent to the residence of former President Bill Clinton and his wife former Secretary of State Hillary Clinton in New York. On Wednesday, a similar package was found outside the home of former President Barack Obama in Washington, D.C.

California Democrats Rep. Maxine Waters and Sen. Kamala Harris were also sent suspicious packages Wednesday. A package addressed to former Attorney General Eric Holder was found at the office of Rep. Debbie Wasserman Schultz, D-Fla. Wasserman Schultz was previously the head of the Democratic National Committee.
