President Obama will hit the road for another economic speech on Tuesday, giving an address on housing in Phoenix, Ariz., before flying to California to appear on “The Tonight Show with Jay Leno.”

The White House on Wednesday announced what will be the latest stop in a series of campaign-style events by the president, one that comes as Congress takes its summer recess and before Obama heads for his own weeklong vacation on Martha’s Vineyard. The president will also visit troops at California’s Camp Pendleton.

White House Press Secretary Jay Carney said Obama would highlight his blueprint to “help responsible homeowners.”

Obama has appeared on late-night talks shows far more than any of his predecessors, a strategy his surrogates contend is necessary to craft a message in today’s media landscape. It will mark Obama’s 6th appearance on Leno’s program, his fourth as president.

Given Obama’s appearance in Southern California, Carney was asked about Democratic San Diego Mayor Bob Filner, who faces a series of sexual harassment allegations and calls to resign.

“I don’t have anything on that,” Carney said.

Noting that Obama was the head of the Democratic Party, Carney was asked again to weigh in.

“I don’t have anything,” he repeated.

For good measure, Carney also refused to comment on New York City Democratic mayoral candidate Anthony Weiner, who is embroiled in a new sexting controversy.
