A more junior member of the committee, Rep. Rick Crawford of Arkansas, will step aside from the panel during impeachment proceedings to make room for Jordan, House GOP Leader Kevin McCarthy announced.

“Jim Jordan has been on the front lines in the fight for fairness and truth,” McCarthy said. “His addition will ensure more accountability and transparency in this sham process.”

The public phase of impeachment kicks off with the first open hearing on Wednesday. Jordan (R-Ohio) is the top Republican on the House Oversight Committee and is known for hostile questioning of witnesses and garnering media attention.

The appointment comes as some Republicans have privately questioned whether Rep. Devin Nunes, the top Republican on the Intelligence Committee, was prepared to mount a solid defense for Trump on the committee, the Los Angeles Times reported.
