The 2012 GOP nominee will attend a luncheon in McLean, Va., according to Cuccinelli's campaign.

"Ken is grateful to have Governor Romney’s support. He's looking forward to sharing ideas with the governor on how to grow Virginia's economy and implement his plan to create 58,000 jobs," Cuccinelli spokesman Richard Cullen says in a statement.

Cuccinelli has lagged behind Democrat Terry McAuliffe in recent polls, and trails him in fundraising heading into the final six weeks of the campaign.
