President Obama will wade into the immigration debate Tuesday morning, dropping his relative silence on the issue as lawmakers prepare to debate the sweeping legislation from the Senate floor.

The “president will again praise the bipartisan progress that continues to be made in the Senate, which has its first floor vote on the bill this week, and highlight the broad coalition of leaders who agree that the shared principles of strengthening and increasing border security, providing an earned path to citizenship, holding employers accountable, and bringing our immigration system into the 21st century must be central to any effort,” said a White House official, previewing Obama’s remarks at 10:20 a.m. Tuesday.

Obama began his immigration push in his weekly address on Saturday.

“The bill before the Senate isn’t perfect,” Obama said. “It’s a compromise. Nobody will get everything they want — not Democrats, not Republicans, not me. But it is a bill that’s largely consistent with the principles I’ve repeatedly laid out for commonsense immigration reform.”

For the most part, Obama has steered clear of immigration negotiations, hoping not to alienate conservatives open to a pathway to citizenship for the nation’s 11 million illegal immigrants. But progressives pushed the president to get more involved.

The administration official also provided the list of political figures, business leaders, law enforcement officials and labor interests who will join the president from the East Room of the White House.
