WASHINGTON -- President Barack Obama will unveil his long-awaited immigration plan Thursday evening, changing rules governing deportations that could affect millions of undocumented immigrants and setting off an explosive battle with Republicans.

Obama's prime-time address will be followed Friday by an event in Las Vegas.

While exact details of his announcement haven't yet been made public, the basic outline of the plan, as relayed by people familiar with its planning, includes deferring deportation for the parents of U.S. citizens, a move that would affect up to 3.5 million people.

The president declared in June he wouldn't wait for Congress to pass a comprehensive overhaul of the immigration system, initially saying he would announce changes by the end the summer.

The decision was delayed until after the midterm elections, when the White House believed it wouldn't be caught up in campaign politics.

But Republicans have expressed deep anger at the anticipated move, saying unilateral action on immigration would forestall any legislative action.
