Rep. Devin Nunes (R-Calif.), who serves as the top Republican on the House Intelligence Committee, will retire at the end of the year and become CEO of Trump's new media organization.

Why it matters: Nunes, once considered a moderate member of the party, became one of the fiercest defenders of former President Donald Trump throughout both of Trump's impeachments and the Intel committee's Russia investigation.

• Trump awarded Nunes the Presidential Medal of Freedom in 2021.
• In a letter to his constituents, Nunes said he was "presented with a new opportunity to fight for the most important issues I believe in," CNN reported.

Driving the news: Nunes will become CEO of "Truth Social" in January.

• He will run the company as regulators are investigating the planned merger between Digital World Acquisition Corporation and Trump's company, according to a recent filing by the SPAC.

California's new congressional districts put Nunes in a district that leans more Democratic, per a draft of the map, SFGate reports.

• Nunes has served in Congress since 2002.
