Rick Wiley, the veteran Republican operative who was dismissed late last month as Donald Trump's national political director, is now working for the Republican National Committee and is helping run its field program, according to three people familiar with the move.

Wiley has begun work at the RNC as a consultant helping oversee the national party's field program, which in the absence of a robust organization by the Trump campaign is taking the lead in building a general-election ground game in battleground states.

Sean Spicer, the RNC's chief strategist, confirmed Wiley's hiring and stressed that he has joined the RNC effort with the blessing of the Trump campaign.

"Rick has been hired as a consultant by the RNC in consultation and agreement with the Trump campaign," Spicer said.

Trump campaign manager Corey Lewandowski referred questions about Wiley to the RNC.

Trump hired Wiley as national political director in April, and his arrival generated much fanfare because he brought significant experience managing campaigns and establishment connections to a campaign that lacked both. But Wiley ran afoul of rival Trump aides and eventually of the candidate himself, who fired Wiley in late May.

Wiley's move to the RNC is a homecoming of sorts. Four years ago, he served as the party's national political director and worked closely with then-nominee Mitt Romney's campaign to build and execute a ground game for the presidential election.

More recently, Wiley served as campaign manager for Wisconsin Gov. Scott Walker's presidential campaign, which ended last fall.
