President Trump's tough talk aimed at political opponents isn't to blame for Saturday's shooting at a Pittsburgh synagogue or last week's mail bomb attacks, according to Vice President Mike Pence.

“Everyone has their own style, and frankly, people on both sides of the aisle use strong language about our political differences,” Pence told NBC News on Satuday, following a campaign stop in Las Vegas. “But I just don’t think you can connect it to acts or threats of violence.”

Pence defended his use of the word "mob" to describe Democrats angry with the Trump administration, saying the country had a proud tradition of facilitating free speech.

“And throughout the history of this country we’ve always had vigorous debates and then we settle those debates in the ballot box," he said. "We don’t settle them through acts or threats of violence like the pipe bombs we saw sent to the Obamas, the Clintons, to CNN, and others.”

At least 11 people were killed and six others wounded, including four police officers, after a gunman walked into the Tree of Life Synagogue in Pittsburgh on Saturday morning and opened fire as he shouted "All Jews must die." The shooting suspect, Robert Bowers, 46, surrendered to authorities and federal prosecutors have filed hate crime charges against him.

The shooting follows Cesar Sayoc, 56, last week being arrested for sending about a dozen pipe bombs to some of Trump's harshest Democratic critics, including former President Barack Obama, former President Bill Clinton, former Secretary of State Hillary Clinton, and former CIA Director John Brennan at CNN.
