Rep. Trey Gowdy defended himself Wednesday against accusations that he acted as an extra lawyer for Jared Kushner when the White House senior adviser privately interviewed with the House Intelligence Committee in its Russia probe.

Gowdy, R-S.C., suggested that Rep. Adam Schiff, D-Calif., the ranking member of the committee who leveled the accusations, is using the Russia investigation to boost his own political profile.

"Adam's frustration [was] that Jared Kushner did not tell him what he wanted to hear from a political ambition standpoint," Gowdy said on CNN. "This investigation has been very good for the Adam Schiff for Senate campaign. But yesterday was not good for him."

According to a report Wednesday from Bloomberg, Schiff told a group of reporters, "Mr. Gowdy took the role as a second attorney for Mr. Kushner."

Schiff's remarks came a day after Kushner, President Trump's adviser and son-in-law, spent three hours in an interview with the committee. After that meeting, Schiff told reporters the interview with Kushner resulted in a "very productive session."

In the CNN interview, Gowdy, who is also chairman of the House Oversight Committee, acknowledged he became frustrated with Democrats' questioning of Kushner.

"What I was tired of was the Democrats asking nonrelevant questions," Gowdy said. "Jared Kushner answered all of their questions. He stayed an hour longer than he was supposed to. The Democrats ran out of good questions, but they didn't run out of questions."
