Darrell Issa has won reelection to his California House seat, the Associated Press reported Monday.
Issa, a Republican congressman, narrowly edged out Democrat Doug Applegate in a race that had been too close to call until Monday afternoon.
The former House Oversight Committee chairman was elected to a ninth term over Applegate, a trial lawyer and retired Marine colonel who served in Iraq. AP reported that Issa has a 2,300-vote lead, according to unofficial returns.
Issa’s victory gives Republicans a 45-seat majority in the House with two Louisiana seats still unclaimed. The state will hold a Dec. 10 runoff election to name representatives of its 3rd and 4th Congressional Districts.
Issa has been a chief antagonist of President Barack Obama. He used his chairmanship of the powerful House Oversight panel to launch investigations into the 2012 attack in Benghazi, Libya, the IRS’s alleged targeting of conservative groups and the flawed launch of healthcare.gov, among others.
