California's newest Congressman Jimmy Gomez has not yet taken his seat in the House, per the Los Angeles Times. He was elected earlier this month in a special election in the state's heavily liberal 34th congressional district.
House Majority Leader Kevin McCarthy has sent a letter to House Minority Leader Nancy Pelosi and California's Secretary of State to figure out why.
McCarthy's take: Gomez is waiting to be sworn in to keep his seat in the California State Assembly in order to help Governor Jerry Brown get a veto-proof majority on a cap-and-trade bill set to hit the floor before mid-July.
Gomez's response: He told Nancy Pelosi he could be sworn in anytime after June 15, barring a family conflict this week. However, given that Congress is about to recess for July 4, the earliest he could now be sworn in is July 10.
