President Trump went to upstate New York on Friday night to boost Bruce Blakeman, the Republican trying to unseat Democratic Gov. Kathy Hochul in November.

At a packed rally at the Oncenter in Syracuse, Trump said Hochul and Democrats "have turned New York into a national embarrassment of high cost, high crime, massive corruption," the New York Post reported. "The people of New York need to clean house in Albany on November 3rd, starting with Kathy Hochul," he said.

Trump promised to work closely with Blakeman. "If Bruce Blakeman, as your governor, calls me to help straighten out in New York City or pretty dangerous parts of this state," he said, "I'll be there within 24 hours, Bruce," according to the Post.

He also went after power bills. "Your energy bills are the highest in the nation," Trump said, and he claimed Blakeman "will cut your electric bills by 70%, 80% and 90%" by tapping the state's oil and gas, the Post reported.

Blakeman, the Nassau County executive, spoke before Trump. He called Hochul "the most pro-criminal governor in America" and pledged to open the state to fracking. "It's drill baby drill," he said. He drew loud cheers when he vowed to sign an order on day one declaring that "New York is no longer a sanctuary state," the Post reported. He also blamed Hochul for Thursday's ICE shooting in the Bronx.

Trump also praised Saritha Komatireddy, the Republican running for attorney general, and attacked Attorney General Letitia James, a Democrat he has long fought with. He told the crowd to say "you're fired" to both Hochul and "that disgusting Letitia dog," NBC News reported.

James's campaign hit back. "Donald Trump is in Syracuse supporting the only attorney general candidate who clerked for Brett Kavanaugh, the man who ended Roe v. Wade," a spokesperson told NBC News. "The contrast is crystal clear and we welcome it."

What we know: Trump is putting his weight behind Blakeman and the state GOP ticket.
What we don't: How his attacks will play with New York voters, who decide on Nov. 3.
