White House spokesman Jay Carney on Tuesday brushed aside questions about former Alaska Gov. Sarah Palin's (R) nationwide bus tour.
Asked about the tour, which began in Washington, D.C., on Sunday, Carney said that the president has been busy with other matters.
"I don’t think he's paying much attention to that," he told reporters during his daily briefing.
Palin is considering a run for the GOP presidential nomination, and many believe she could contend for the chance to face Obama in 2012.
The ex-governor took pointed jabs at Obama in 2008 as the GOP's vice presidential nominee and continued to campaign for Republicans in 2010 with an anti-Obama message.
But Palin has not said whether she will enter the field; likewise, the White House appears reluctant to comment on her.
While many believe Palin's tour is designed to boost interest in her potential candidacy, she says it is not related to a possible campaign and has declined to take significant shots at the president during the tour.
