(CNN) - House Speaker John Boehner met with Mitt Romney in Atlanta on Monday, and will campaign with the Republican presidential candidate this Sunday in Troy, Ohio, sources told CNN.
The hour-long session was the first face-to-face meeting of the two since Boehner endorsed Romney in April.

The city of Troy is in Boehner's Ohio Congressional District and falls on the route for Romney's bus tour next week.
Sen. Rob Portman, another member of the state's delegation to Washington, will attend all three of Romney's stops in Ohio, a source with knowledge of the events said. He is considered one possible vice presidential pick to join Romney on the GOP ticket.
The two met privately, a source familiar with the meeting told CNN, and had a "friendly" session, and "discussed the need to work together."
This week the House of Representatives is on a week-long recess, and Boehner, as he does on most Congressional breaks, is on the road raising money for House GOP candidates. His swing this week is along the East Coast and included Atlanta, where he met with Romney before the presumptive GOP nominee was attending his own fund-raiser.
Citing his role as the chairman of the Republican National Convention, Boehner deliberately stayed out of the divisive GOP primary fight earlier this year. But in April when it became clear that Romney would be the party's nominee, Boehner endorsed the former Massachusetts governor. The speaker said then that Romney's economic policies "contrast sharply with the failed economic policies of President Obama."
