Hager, the groom who turns 30 on the eve of his wedding day and graduates with a master's degree the following week, proposed at sunrise to Jenna at Acadia National Park last summer. The former aide to Karl Rove knows the White House well and met her during the 2004 re-election campaign.
Jenna has tried to shed the party-girl image she got while in college. In the fall of 2006, she was hired as an intern by UNICEF to teach and chronicle the stories of children in four countries.
Last year, she became an author after writing a book, "Ana's Story," based on one of the young women she'd met in Latin America.
Jenna said she will return to teaching after the wedding. The couple plans to settle in Maryland.
The Baltimore Sun reports Hager bought a $440,000, two-story, 128-year-old row house south of downtown Baltimore.
The nearly 2,000-square-foot house is believed to have been a dry cleaners and a candy shop, has exposed brick walls, a fireplace and an attached garage.
