President Donald Trump’s advisers are pushing him to defy congressional investigations in hopes of luring Democrats into escalating a fight that they say will turn voters against the party in the 2020 elections.

The advisers are counting on news coverage of the battle with Congress — including Democrats’ raising the possibility of impeachment — distracting attention from candidates vying to replace Trump, and are portraying the president as a victim of partisan gamesmanship.

The House Judiciary Committee on Wednesday is set to vote on holding Attorney General William Barr in contempt for missing a subpoena deadline to turn over an unredacted version of special counsel Robert Mueller’s report on allegations of Russian connections to Trump’s 2016 campaign and the president’s possible obstruction of the investigation. Trump advisers also see an upside from House Speaker Nancy Pelosi’s warning Tuesday that the administration’s defiance of subpoenas could lead to impeachment proceedings.

“It won’t turn out well for them,” said Trump’s campaign communications director Tim Murtaugh. “The fact that Democrats want to continue the witch hunt shows that they have no interest in legislating and only care about politics.”

The administration further advanced its strategy Tuesday by telling former White House Counsel Don McGahn not to comply with a subpoena from House Democrats to turn over documents. Trump tweeted over the weekend that special counsel Robert Mueller shouldn’t testify to Congress, and on Monday, Treasury Secretary Steven Mnuchin refused a requests to turn over Trump’s tax returns.

The effort to turn Trump’s potential liabilities into a 2020 election advantage carries risks. The president’s refusal to turn over documents could lead voters to conclude he has something to hide and focus attention on the Mueller investigation, which painted an unflattering picture of Trump.

Pelosi said at an event at Cornell University on Tuesday that Trump’s strategy poses a dilemma for Democrats. “Trump is goading us to impeach him, that’s what he’s doing every single day,” she said. “We can’t impeach him for political reasons, but we can’t not impeach him for political reasons.”

Not everyone in her party agrees. Sen. Elizabeth Warren of Massachusetts, who is running for president, on Tuesday called for impeachment proceedings to begin and said politics shouldn’t be a factor.

“If any other human being in this country had done what’s documented in the Mueller report, they would be arrested and put in jail,” Warren said on the Senate floor Tuesday.
