The Associated Press reports that Montana Gov. Steve Bullock will try to unseat first-term Republican Sen. Steve Daines, a senior adviser said Monday, giving Democrats a boost in their effort to take control of the Senate in November.

Bullock's decision to run is an abrupt about-face made at the last minute for the two-term governor, who ended his long-shot bid for president in December and had repeatedly insisted he had no interest in running for the Senate.

But Bullock had come under increasing pressure, including meeting with former President Barack Obama in Washington and with Senate Minority Leader Chuck Schumer. Schumer, of New York, recently traveled to Montana to meet with Bullock. Bullock reportedly weighed the matter with his family over the weekend before making his decision.

Democrats need to win four seats that are now held by Republicans, without losing any that they are defending, to win outright control of the Senate. If President Donald Trump is defeated, the Democrats would need a net gain of three seats and the vice-president's tie-breaking vote for control.

Bullock planned to walk across the hall from his office in the state Capitol to file his paperwork on Monday, the final day for candidates to register in Montana, senior adviser Matt McKenna said.

A campaign ad released Monday said Bullock wants to “make Washington work like Montana” and touted the state's low unemployment and expanding economy during his tenure as governor. The ad also highlighted legislative achievements, such as Medicaid expansion and revising the state's campaign finance laws to increase reporting requirements by political committees.

Bullock is running for the seat formerly held by Democrat Max Baucus. Baucus, the former U.S. ambassador to China, said the meeting of Schumer, Bullock and their wives in Big Sky was key to the decision, but he did not know the substance of those talks.

Baucus also said it “probably helped” that former Vice President Joe Biden has surged in the Democratic presidential primary race, making it less likely that self-described democratic socialist Vermont Sen. Bernie Sanders will lead the ticket in the strongly pro-Trump state.

Bullock becomes the most prominent candidate in the Democratic primary race, which also includes public health expert Cora Neumann and Helena Mayor Wilmot Collins.

Daines has the backing of Trump, for whom the state overwhelmingly voted in 2016. Trump has tweeted his support for Daines, who recently met with the Republican president at the White House.

Daines spokeswoman Julia Doyle expressed confidence in the Republican's reelection chances last week amid reports that Bullock was considering entering the race.

But, as Bullock frequently pointed out during his presidential campaign, Bullock was the only Democratic governor to win reelection in a state Trump won in 2016. Trump also traveled to Montana four times to campaign against incumbent Democratic Sen. Jon Tester in the 2018 election, but Tester won, anyway.

Republicans started the campaign against Bullock last week by saying he caved to party leaders to run for a job he doesn't want.

“Gov. Bullock isn't actually interested nor would he find it compelling or enjoy being a U.S. Senator — he said so himself, he simply couldn't resist the pressure from Barack Obama and Chuck Schumer,” Montana Republican Party Chairman Don Kaltschmidt said in a statement released then.

Senator Steve Daines' office provided the following statement:

“We’re going to win this race because Steve Daines is always on Montana’s side fighting for more high-paying jobs, against big government and defending Montanans’ way of life.  From protecting our pocketbooks, veterans, public lands and Second Amendment Rights, Daines always puts Montana first and Montanans know they can always trust him to continue doing so when he’s re-elected in November," said Daines Campaign Manager, Shane Scanlon.
