The House is giving lawmakers and the White House more time to try to undo the congressional impasse on President Obama's trade agenda. But leaders of both parties say there's no obvious pathway yet. 

The House voted 236 to 189 Tuesday on a procedure that gives lawmakers six more weeks to revisit Friday's stunning vote that rejected Obama's initiative. He wants "fast track" trade negotiating authority. 

Unions and liberals strongly oppose him. They helped fuel Friday's insurrection among House Democrats. 

Speaker John Boehner told reporters Tuesday that he is committed to enacting fast track "as soon as possible." But he said no solutions have been found. 

Republicans voted overwhelming for Tuesday's procedural vote after Boehner privately berated several of them for opposing the GOP leadership on similar such questions.
