Washington (CNN) Republican Sen. Rand Paul, before a raucous crowd on Monday, demanded members of the media print the identity of the anonymous whistleblower at the heart of the House impeachment inquiry into President Donald Trump's dealings with Ukraine.

"I say to tonight to the media: do your job and print his name," Paul, a Kentucky Republican, yelled during a rally Trump held in support of Republican Gov. Matt Bevin ahead of Tuesday's gubernatorial election. The crowd of Trump supporters, many donning "READ THE TRANSCRIPT" shirts, erupted into applause and cheers, and some chanted "Do your job!" and pointed toward the area where members of the press gathered to cover the event.

Paul told the crowd "we also now know the name of the whistleblower," but did not provide any personal knowledge of the person's identity, before going on to echo baseless claims of wrongdoing by former Vice President Joe Biden and his son, Hunter. "The whistleblower needs to come before Congress as a material witness because he worked for Joe Biden at the same time Hunter Biden was getting money from corrupt oligarchs," Paul said. There is no evidence of wrongdoing by either Joe or Hunter Biden.

Several other Republicans have called for the whistleblower's identity to be revealed -- despite federal laws to protect individuals who file complaints -- but the sitting senator's insistence before a chanting crowd stands as one of the most forceful public calls yet. His comments drew swift condemnation from Democrats, who argue the person's identity has no bearing on the allegations lodged against the President.
