A White House spokesperson mocked Wednesday’s House Oversight and Accountability Committee with tweets as it was taking place and got into a back and forth with the committee's Twitter account as the hearing was taking place.

"Despite years of obsession and countless wasted taxpayer dollars on a wild goose chase, the House GOP hasn't offered a single credible piece of evidence of wrongdoing by the President," White House spokesman for oversight and investigations Ian Sams tweeted Wednesday. The message went out as lawmakers heard from two IRS whistleblowers who said their their investigation into Hunter Biden’s tax records was obstructed for political reasons.

"This waste of time reflects the extraordinarily misplaced priorities of House Rs," Sams said.

The House Judiciary Committee’s Twitter account responded to Sams by implying the Biden White House was nervous about the hearing.

"The White House is TERRIFIED of the Biden Family's corruption being exposed," the committee posted. "Makes you wonder, why?"

Sams responded with a joke. "Your caps lock is on," he said.

Sams addd in a statement to Fox News Digital that Biden has "upheld his commitment" to make sure the investigation would proceed on a non-partisan basis.

"Instead of wasting time on politically-motivated attacks on a Trump-appointed U.S. Attorney, the rule of law, and the independence of our justice system, House Republicans should join President Biden to focus on the issues most important to the American people like continuing to lower inflation, create jobs, and strengthen health care," he said. "There are real issues Americans want us to be spending our time on, and President Biden believes we can work together to make real progress, if House Republicans would make an effort instead of constantly staging partisan stunts to try to damage him politically."

Two IRS whistleblowers – special agent Joseph Ziegler and supervisor Gary Shapley – testified during a contentious hearing that their investigation into the business practices of Hunter Biden was stonewalled by the Department of Justice and that Biden should have been charged with a felony but was not for political reasons.

Ziegler also confirmed during the testimony that the Biden family received $17 million over five years from various foreign countries.

"What were the Biden's selling?" Comer posted on Twitter during the hearing.

Democrats in the hearing dismissed any impropriety and instead spent much of their questioning pointing out accusations against former President Donald Trump.
