Democratic presidential frontrunner Hillary Clinton said on Friday that she condemned recent violence against Donald Trump supporters, but she also accused the presumptive GOP nominee of inciting violence in other incidents.

Clinton told CNN’s Jake Tapper in an interview that Trump “set a very bad example” by not condemning violence committed by his supporters last year.

“I condemn all violence in our political arena,” Clinton said. “I condemned it when Donald Trump was inciting it and congratulating people who were engaging in it.”

Pro-Trump supporters and protesters clashed at Trump’s Thursday night rally in San Jose, Calif., where Trump fans were filmed being punched and kicked outside of the event. Clinton’s campaign chair, John Podesta, also condemned the violence Thursday night.

“He created an environment in which it seemed to be acceptable for someone running for president to be inciting violence, to be encouraging his supporters. Now we’re seeing people who are against him responding in kind,” Clinton told Tapper. “It should all stop. It is not acceptable.”

Clinton is in a tight race with Vermont Sen. Bernie Sanders in California ahead of state’s June 7 primary. A win there by Clinton next week could make it hard for Sanders to continue his campaign in the face of increasingly daunting odds.

Clinton said she is expecting a strong performance in the Golden State and will move forward attempting to unite her party.

“After Tuesday, I am going to do everything I can to reach out to try to unify the Democratic Party, and I expect Sen. Sanders to do the same,” Clinton said. “And we will come together and be prepared to go to the convention in a unified way to make our case, … to go into the general election to defeat Donald Trump.”
