WASHINGTON (AP) — The White House and a bipartisan group of senators will launch separate efforts next week to jumpstart negotiations to overhaul the immigration system, an issue that has languished in Washington for years.

Obama will start his second-term immigration push during a trip to Las Vegas Tuesday. The Senate working group is also aiming to outline its proposals at about the same time, according to a Senate aide.

Even before those plans are formally unveiled, there is emerging consensus on several key components, most notably the need for some kind of pathway to citizenship for the 11 million illegal immigrants already in the United States. The White House and Senate Democrats favor addressing immigration through a broad package of legislation, while some Republicans lawmakers prefer to tackle the issue through several separate bills.
