IRS whistleblowers Gary Shapley and Joseph Ziegler will attend President Donald Trump's address to a joint session of Congress on Tuesday night.

Their appearance in House chambers was announced by House Oversight Chairman James Comer and House Judiciary Committee Chairman Jim Jordan.

"Gary Shapley and Joseph Ziegler embody the highest standards of the federal workforce," the Republican congressmen said in a joint statement. "They are honorable public servants who risked their careers and livelihoods to expose misconduct and politicization in the federal criminal investigation of Hunter Biden."

IRS Supervisory Special Agent Shapley and Special Agent Ziegler investigated potential financial crimes by Hunter Biden, when his father, Joe Biden, was president, but were removed from the probe after telling Congress that the Justice Department interfered with their investigation.

"We will continue to stand with these brave whistleblowers and are proud to welcome and honor Gary and Joe as our guests at President Trump’s address before a joint session of Congress,” Comer and Jordan's statement concluded. 

Shapley and Ziegler said that they were honored to be invited. 

"It's an honor for us to be invited to President Trump's joint address to Congress by chairmen Comer and Jordan," they said in a joint statement. "We appreciate their steadfast support and recognition of the sacrifices we made for telling the truth and the retaliation we are still suffering for blowing the whistle."
