Senate Democratic lawmakers thought they had dispatched former California Rep. Darrell Issa by blocking his nomination to a Trump administration post. But now he’s about to be their colleague, again, on Capitol Hill.

Prior to running for former GOP Rep. Duncan Hunter Jr.’s open seat in California’s 50th Congressional District this year, the 18-year California Republican House member left Congress before the 2018 mid-term cycle. Issa declined to seek reelection that year in a different district to the north, which has since gone Democratic.
