(The White House)

President Obama met with former president George H. W. Bush and his son, former Florida Gov. Jeb Bush, at the White House this evening.

Their Oval Office meeting was not on the president's official schedule for today but was made public when the White House released a photo of the meeting on its Flickr site. The former president and his son are in town for the annual Alfalfa Club dinner Saturday night.

According to a White House official, "The three men enjoyed a personal visit in the Oval Office, as they have done on previous occasions when President Bush is in Washington."

The meeting came just days before the Republican Florida primary. The popular former governor has yet to endorse a candidate in the tight race in his state.

Earlier in the week, Jeb Bush warned the Republicans vying for the White House to tone down their assaults.

"I think there's a point past which Republicans and independent voters get turned off by this fierce primary spilling over into personal attacks," he told CNN. "I would hope that both Gov. Romney and Speaker Gingrich would stay away from that."
