FARGO, N.D.: President Donald Trump urged voters on Wednesday to fire “liberal Democrat” Sen. Heidi Heitkamp in November, claiming that she promised to be an independent mind but instead has voted in lockstep with her party leadership and against his agenda.

Trump called instead for the election of Republican U.S. Rep. Kevin Cramer, one of his staunchest allies in Congress.

“When Heidi ran for office, she promised to be an independent vote for the people of North Dakota,” Trump said to an arena packed with cheering supporters in Fargo. “Instead, she went to Washington and immediately joined Chuck ... and Nancy,” a reference to Democratic congressional leaders Sen. Chuck Schumer and Rep. Nancy Pelosi.

But Heitkamp, one of the most vulnerable incumbents seeking re-election this year, is considered a moderate who is one of the least reliably partisan Democratic votes in the Senate. She’s largely backed the oil-rich state’s corporate interests on energy and has opposed some restrictions on guns. She voted to confirm 21 of Trump’s 26 Cabinet-level nominations.

The president, however, noted Heitkamp’s votes against tax cuts he signed into law in December as well as the GOP’s long-sought goal to undo the health care program enacted by President Barack Obama.

“You need a senator who doesn’t just talk like they’re from North Dakota but votes like they’re from North Dakota,” Trump bellowed. “That’s what you need and that is Kevin Cramer.”

Called to the microphone by the president, Cramer thanked Trump for rolling back federal regulations, cutting taxes and, “on behalf of the most vulnerable forgotten people, the unborn babies, thank you for standing for life.”

He pledged to always be with Trump.

“And on these very important North Dakota values, you never have to wonder where I’ll be because I’ll always be with them and with you 100 percent of the time,” Cramer said.

Heitkamp stood next to Trump at the White House when he signed a banking deregulation bill into law, alarming some Republicans who worried he was becoming too close to her.

Trump urged the election of more Republican senators, saying the current 51-49 GOP majority is a “problem.” Most legislation needs 60 votes to get through the Senate, and Democrats have refused to go along with much of what Trump and the Republicans have proposed.

“It’s a very tough situation,” he said. Trump added that “we have to hold the House and maybe even increase it, and I think we’ll be able to do it.”
