President Obama held a meeting on immigration reform Tuesday afternoon that included a wide range of guests, from the Rev. Al Sharpton to former senator Mel Martinez (R-Fla.).

The attendees at the hour-long session were mostly advocates of creating a path to citizenship for immigrants who are here illegally, an approach Obama favors.

It was not clear exactly how the group was composed or why it met Tuesday, as Obama has not announced any new plan to push for immigration reform. Republicans in Congress are likely to strongly oppose any proposal to make it easier for illegal immigrants to become citizens.

“The President reiterated his commitment to comprehensive immigration reform,” the White House said in a statement after the meeting.

The meeting comes just before Obama heads for campaign-style stops in California and Nevada, two states with large Hispanic populations.
