Just hours after stepping down as US House majority leader, Republican Representative Eric Cantor announced he would resign from his congressional seat later this month.
Establishment heavyweight Cantor lost his seat to an even more conservative but virtually unknown Tea Party-backed challenger in a June election amid deep divisions within the Republican Party ahead of November's congressional vote.
But he had been expected to keep his seat until his term ends in January.
"I want to make sure that the constituents in the Seventh District will have a voice in what will be a very consequential lame-duck session," Cantor told the Richmond Times-Dispatch late Thursday.
Cantor said he has asked Virginia Governor Terry McAuliffe to call a special election for his district coinciding with the November 4 general election.
Holding such a special election for his seat in November would allow the winner to take office immediately, rather than in January with the next congressional session.
"That way he (the winner) will also have seniority, and that will help the interests of my constituents (because) he can be there in that consequential lame-duck session," Cantor explained.
Kevin McCarthy replaced Cantor as House majority leader.
Cantor, who had been the only Jewish Republican in Congress, has expressed frustration at divisions in Washington and the glacial pace in Congress.
"There is a lot of business that is still to be done," he told the Richmond Times-Dispatch. "I wish that Washington would act quicker."
Cantor declined to reveal his plans for life after Congress.
