Aides said that Mr. Obama will make the announcement in the White House briefing room. The aides said the president isn’t expected to announce major policy decisions, but will lay out how the administration will move forward on the issue.

Mr. Biden will be at the briefing Wednesday and could be essential to getting any changes through Congress, as he has decades of experience as a senator and is often Mr. Obama’s go-to person when the president seeks to build support on Capitol Hill.
