As the impeachment inquiry moves from the House Intelligence Committee chaired by Rep. Adam Schiff (D-CA) to the House Judiciary Committee chaired by Rep. Jerry Nadler (D-NY), top House Judiciary Republican Rep. Doug Collins (GA) says Schiff is the most important witness the GOP wants to interview - after the whistleblower who sparked the entire affair approached Schiff's committee before filing an official complaint.

"My first and foremost witness is Adam Schiff," Collins told "Fox News Sunday," adding that Schiff had "compared himself in the past to a special counsel," while noting that former special prosecutor Kenn Starr testified during the GOP-controlled House's impeachment of President Clinton, according to The Hill.

"[Schiff] has put himself into that position," added Collins. "If he chooses not to [testify], then I really have to question his veracity in what he’s putting in his report."

"Why are they hiding the stuff from us? If they think they have such a case, give us all the materials and don't let Jerry Nadler write a crazy letter that says on the 6th, let us know who your witnesses are. We don't even have the information from the Intel Committee yet. This is why this is a problematic exercise and simply a made-for-TV event coming on Wednesday."

According to Politico, Schiff will begin circulating a report on Monday within the House Intelligence Committee which will contain the conclusions of his panel's investigation of President Trump's request that Ukraine investigate Joe Biden and his son Hunter.
