President Obama is expected to express his support today for a sweeping blueprint for immigration reform backed by a bipartisan group of senators. The Senate plan includes a path to citizenship for the estimated 11 million undocumented people in the United States, but also demands tougher border enforcement and a system for tracking those who overstay visas. Some have condemned the plan’s exclusion of LGBT couples from the right to sponsor a foreign-born partner so they can obtain residency. Democratic Sen. Chuck Schumer of New York and Arizona Republican Sen. John McCain announced the Senate proposal on Monday.

Sen. Chuck Schumer: “We still have a long way to go, but this bipartisan blueprint is a major breakthrough. It’s our hope that these principles can be turned into legislation by March and have a markup by Chairman [Patrick] Leahy’s committee with the goal of passage out of the Senate by late spring or summer.”

Sen. John McCain: “We have been too content for too long to allow individuals to mow our lawn, serve our food, clean our homes, and even watch our children, while not affording them any of the benefits that make our country so great. I think everyone agrees that it’s not beneficial for our country to have these people here hidden in the shadows.”

President Obama will outline his ideas for immigration reform today in a speech in Las Vegas. While Obama is said to differ from the senators on several issues, administration officials said today’s speech will focus instead on rallying public support for reform.
