“This trial is about protecting the presidency from the tyranny of the House majority — these are bogus charges, they are not impeachable offenses, and we expect that the Senate will acquit,” said Jenny Beth Martin, honorary chairman of Tea Party Patriots Action, who has worked to bring the groups together. “Senators of both parties must make it clear — Speaker Nancy Pelosi and Congressmen Adam Schiff and Jerry Nadler cannot be allowed to corrupt the Constitution.”

The groups are supplementing efforts by the Trump campaign, which is raising money through fundraising texts, placing targeted Facebook ads and attacking House leaders on Twitter.

“Pres. Trump: The Senate Impeachment Trial is underway,” one text read. “I need you, friend. Let’s raise $2 MILLION in 24 HOURS.”

“I am facing UNPRECEDENTED obstruction and harassment from the Liberal Mob and the Fake News,” a Facebook ad read. “I’ve been exonerated twice, but the Democrats are still calling for impeachment because it’s their only hope. Please sign my Official Petition to be on the list of American Patriots who stand with me against these baseless lies.”

Together, Trump’s campaign and the Republican National Committee have spent more than $11 million on impeachment-related ads since the inquiry began in September, according to the RNC. They have also engaged in calls, texts and hundreds of Facebook ads offering a personalized “Impeachment Defense Membership Card” and “Impeachment Polls.” There’s even impeachment-inspired apparel at Trump’s online store.

During the impeachment proceedings, Trump was accused of conditioning a much-desired White House meeting for Ukraine’s leader, as well as millions of dollars in military aid, on Kyiv launching an investigation into rival Joe Biden and his son Hunter. Trump and his allies counter that the desired probe was part of a broader effort to eradicate corruption and uncover foreign wrongdoing in the 2016 presidential race.

The House approved two articles of impeachment — abuse of power for soliciting foreign interference in the 2020 election and obstruction of Congress for blocking the House’s efforts to investigate. The articles were approved along a near party-line vote.

The trial kicked off in earnest on Tuesday and is expected to last at least into next week, depending on whether the Senate decides to call witnesses.

As the trial got underway, the Presidential Coalition, an affiliate of Citizens United that claims to educate Americans about “principled conservative Republican leadership,” launched $200,000 worth of digital ads that will appear this week attacking Manchin, Jones, Peters and Sinema, according to the group.

The group plans to spend $200,000 each week on to continue its ad buy until the trial is over.

“They’re wasting millions on a partisan witch hunt to reverse the 2016 election. They know they can’t compete so they try to impeach,” the narrator says in one of their ads, which resemble the ads the group ran ahead of the House impeachment vote. “President Trump has been fighting for us. Now it’s time to fight for him.”

America First Policies, which supports Trump’s policies, is spending $450,000 on TV and digital ads in Alabama targeting Jones, who is considered the most vulnerable incumbent senator in 2020. The group plans to air a total of $1 million in ads across three states, including Michigan and Pennsylvania, as the trial continues.

“The radical left’s impeachment obsession. It’s a shameful witch hunt. And Doug Jones?” a narrator says in the ad. “Instead of fighting for our values, instead of confirming conservative judges, instead of securing our borders by funding the wall, Jones is siding with them.”
