As the House's formal impeachment inquiry moves rapidly forward, President Trump and his 2020 campaign are doubling down on their defenses and attacking critics with language that has raised questions about the president's use of social media.

Treason, for instance, has been used numerous times by Trump as a charge against top Democrats and the whistleblower, whose revelation about the White House's July phone call with the Ukranian president sparked the impeachment probe.

"Trump will use whatever word he feels will fit the moment and the cause," said Erin Perrine, the deputy communications director for Trump's reelection campaign. Perrine also slammed the media for "breathlessly covering" the use of the word treason while ignoring more pertinent issues.

Treason isn't the first heated term that has been condemned. Trump has also been criticized for using words like spy and coup — both of which can be considered treason under U.S. law and are punishable by death.

Sen. Kamala Harris (D-Calif.), a 2020 presidential candidate, sent a letter on Tuesday to Twitter CEO Jack Dorsey, saying that Trump's rhetoric amounted to "blatant threats" and urged the company to suspend the president's account for violating its standards. Twitter told Cheddar that it has received the letter and intends to respond.

Hey, @jack. Time to do something about this. https://t.co/es2fJ5PNRV

"We need a civil society, not a civil war," Harris wrote. "When this kind of abuse is being spewed from the most powerful office in the United States, the stakes are too high to do nothing."

Critics of impeachment have condemned Democrats for using hyperbolic diction of their own. Rep. Maxine Waters (D-Calif.) — chairwoman of the House Financial Services Committee, one of the panels probing impeachment — for instance, drew criticism for tweeting Tuesday that Trump should be imprisoned and "placed in solitary confinement." In the same tweet, Waters also lambasted Trump's use of "filthy talk" and "mob language."

At a press conference with House Speaker Nancy Pelosi (D-Calif.) on Capitol Hill Wednesday, Chairman of the House Intelligence Committee Rep. Adam Schiff (D-Calif.) said that Trump's comments are "incitements of violence" and are intended to intimidate the whistleblower, who remains anonymous. Pelosi echoed the sentiment, saying that the president "does not realize how dangerous" his remarks are.

The Trump campaign, however, says it is well in its right to defend the administration as it sees fit, and counter what it views as a partisan crusade.

"We were well prepared for when Nancy Pelosi finally took the Thelma and Louise approach and drove right off the impeachment cliff," Perrine said. "We stand here … ready to fight on behalf of the president and get the facts out there."

Trump's re-election team is also using impeachment to garner support from Trump voters; especially on Facebook where the campaign has run nearly 2,000 ads mentioning impeachment in the last week, according to the platform's Ad Library. The campaign, Perrine said, took in $15 million in the three days that followed Pelosi's announcement of a formal impeachment inquiry.

Trump's use of Facebook — seemingly effective from a financial stance — has roiled Democrats, who claim the platform is allowing the president to spread misinformation.

"We know that Trump has an utter disregard for the truth," Seema Nanda, the CEO of the Democratic National Committee, told CNN this week, adding that Facebook allows Trump "to mislead the American people on their platform unimpeded."

Trump's 2020 blitz on Facebook, and the Democrats ire, come just days after Facebook announced that it will not fact-check posts or advertisements from politicians.

"It is not our role to intervene when politicians speak," Nick Clegg, Facebook's vice president of global affairs and communications, said in a speech. "In open democracies, voters rightly believe that, as a general rule, they should be able to judge what politicians say themselves."
