<p>WASHINGTON - House and Senate lawmakers rallied yesterday behind legislation that would legalize as many as 500,000 illegal immigrants employed as farmworkers, but the Bush administration has yet to endorse the measure.</p>
<p>Sen. Larry Craig, R-Idaho, and Sen. Edward Kennedy, D-Mass., the bill's chief sponsors, are urgently working to get the measure onto the Senate floor before the end of the year. They are trying for support from at least 60 senators. So far, the bill has attracted 54 sponsors from both parties.</p>
