RNC spokeswoman says party has seen 'groundswell' of support amid impeachment inquiry

A spokeswoman for the Republican National Committee (RNC) on Thursday told Hill.TV that President TrumpDonald John TrumpMnuchin knocks Greta Thunberg's activism: Study economics and then 'come back' to us The Hill's Morning Report - House prosecutes Trump as 'lawless,' 'corrupt' What to watch for on Day 3 of Senate impeachment trial MORE’s reelection campaign has seen an influx of support as the House holds public hearings in its impeachment inquiry into the president.

“We’re seen a huge groundswell of support,” Liz Harrington said, pointing to the campaign’s own internal polling.

“People are outraged. People are so tired of the same game because this has been going on since before he was even inaugurated,” she added.

Harrington also argued that the vast majority of Americans are more concerned with issues other than impeachment, pointing specifically to the economy and Trump's proposed trade deal with Mexico and Canada.

“What independents care about — most Americans care about — are issues that nothing’s being touched by the Democrats,” she said.

According to an average of polls by FiveThirtyEight, 46.5 percent of Americans support impeaching Trump, compared to 45.5 percent who don’t support such a move.

Support for impeachment, meanwhile, appears to be slipping in some key battleground states like Wisconsin.

A Marquette Law School poll released Wednesday showed that 40 percent of Wisconsin voters believe that Trump should be impeached and removed from office, which marks a 4-point dip from a similar poll conducted in October.

Harrington’s comments come as House Democrats conduct public hearings as part of their ongoing impeachment inquiry into Trump’s dealings with Ukraine.

The Democratic-led probe took a major turn Wednesday after U.S. Ambassador to the European Union Gordon SondlandGordon SondlandSenate rejects subpoenaing Mulvaney to testify in impeachment trial The Memo: Day One shows conflicting narratives on impeachment GOP rejects effort to compel documents on delayed Ukraine aid MORE testified that Trump sought a clear “quid pro quo” with Ukraine, conditioning a White House visit for political investigations into Democrats.

Trump later dismissed Sondland's testimony, claiming that he didn't know the ambassador very well.

"I don’t know him very well," Trump told reporters outside the White House. "I have not spoken to him much. This is not a man I know well. He seems like a nice guy though. But I don't know him well."
