Former California Rep. Darrell Issa announced he is running to unseat Rep. Duncan Hunter in a San Diego-based seat as the incumbent faces federal corruption charges.

Issa served in the House from 2001 to 2019 representing a suburban district in northern San Diego County and southern Orange County. He became a national figure as the chairman of the House Government Reform and Oversight Committee during the Obama years, when he routinely clashed with the administration over issues related to the Fast and Furious scandal, the IRS’ targeting of conservative political organizations, and the attack on the U.S. Embassy in Benghazi, Libya, among others.
