President Donald Trump returned to his home state of New York and bashed Democratic Gov. Andrew Cuomo and Sen. Kirsten Gillibrand while stumping for the reelection of Rep. Claudia Tenney (R-N.Y.).

Cuomo, a frequent Trump critic, is running for his third term this fall. Gillibrand is running for her second full term.

Trump wished "good luck" to Republican U.S. Senate candidate Chele Farley, who is opposing Gillibrand and was in the audience at the Tenney event.

"I know your opponent very well. She's been up to my office for campaign contributions," Trump riffed, referring to when he was a business mogul in the state.

Trump expressed doubt as to whether Gillibrand has gotten anything of substance done for New Yorkers and told the crowd Farley would be an ally of theirs in Washington.

Trump said New York State's taxes would also be much lower if Cuomo "would've allowed a little bit of fracking" for natural gas in the Upstate and Southern Tier.

He said that because of Cuomo's insistence against the practice, Pennsylvania and Ohio have been taking advantage of the reserves which he said cross state lines.

"This place is just so sad, we just have the potential to be better than anybody," Trump said of his home state.

Trump said that prior to running for president, he was considering a run for governor: "I said with the use brainpower and common sense, you people could've had a boomtown up here."

Last year, the president's son, Donald Trump Jr., reportedly considered running against Cuomo in his current race.

Trump added that Cuomo "wants to end your Second Amendment" protections in New York, and that the governor once called to say he was "never" going to run for president against him.

"Oh, please do it," Trump said of Cuomo.

Cuomo previously said in a radio interview that "far-right" conservatives who are "pro-gun" or "anti-gay...have no place in the State of New York."

Cuomo faces actress Cynthia Nixon in the Democratic primary -- the winner of which will oppose Republican candidate and Dutchess County Executive Marc Molinaro.
