Harry Reid: 'No more time for delaying tactics'
The Democrat-controlled US Senate is seeking a vote on its plan to raise the nation's $14.3tn (£8.7tn) debt limit, which could determine whether a deal to avoid government default is possible.
Senate leaders want a prompt vote so the plan can be passed on Sunday.
The debate comes a day after the Senate rejected a rival Republican bill passed in the House of Representatives.
"There is no more time for delaying tactics", Senate Majority Leader Harry Reid told a press conference on Capitol Hill, Washington.
