For the second time in as many weeks, a Senate Democrat considered vulnerable in the 2018 elections is preparing to face pressure from President Trump on tax reform in her home state.

Heidi Heitkamp, who represents North Dakota, issued a statement Friday that she was "glad to welcome" Trump to the state next week. Her constituents are "eager to hear more about his tax reform plan," she said.

Heitkamp stopped short of saying that she was prepared to work with the White House on tax legislation. But she sounded more conciliatory than Democratic leader Chuck Schumer, who said this week that Democrats were prepared for a "big fight" with Trump over taxes.

The White House hasn't officially announced that Trump will travel to North Dakota next week. But Bismarck police are working with the Secret Service in anticipation of a visit Wednesday, according to the Bismarck Tribune.

Trump economic adviser Gary Cohn said Friday morning that Trump was going to travel again next week to promote tax reform.

This week, Trump flew to Springfield, Mo. to talk taxes. During his speech, he specifically told audience members to vote out Democratic Sen. Claire McCaskill if she did not vote with Republicans on tax reform.

The president did not similarly lean on Democrats to vote for the GOP healthcare bill.

McCaskill, thought to be the Democrat most at risk of being unseated next year, projected a willingness to work with Trump ahead of that visit. "I'm looking forward to working with him to make bipartisan tax reform a reality," she said then.

On Friday, Heitkamp said she has been "pushing for both sides of the aisle to work together in Congress toward permanent, comprehensive solutions that will do away with loopholes and handouts for special interests and instead promote our small businesses, farm economy and energy industries with the fiscally responsible reforms they need to grow and expand."

Administration aides have said that Trump will make an effort to travel to Midwest states to try to increase the pressure for Democratic senators to vote for tax reform.
