Henry Hager and Jenna Bush

Washington ? Jenna Bush is getting married – to a former Karl Rove intern.

The 25-year-old first daughter was engaged Wednesday to Henry Hager, 29, a former White House and Commerce Department aide and son of Virginia’s Republican Party chairman.

Hager, who also worked for the Bush-Cheney re-election campaign, popped the question in Maine.

A White House statement Thursday said, “No wedding date has been set.”

Hager will return to the University of Virginia’s Darden School of Business this fall.

It has been a more than 2 1/2-year courtship by Hager, who was once written off as “not a serious boyfriend” by his future mother-in-law.

Because there is no date set, no one is saying for sure if they will take their vows at the White House or opt for an Atlantic backdrop in Kennebunkport.

A White House wedding would be the first for a president’s daughter since Tricia Nixon married Edward Cox in 1971 in the Rose Garden.
