The White House has warned that President Obama could veto a debt limit plan proposed by top House Republicans.
Meanwhile, Speaker John Boehner’s plan to trim public spending and raise the limit met with resistance from rank-and-file members of his own party.
A House of Representatives vote on the plan was delayed from Wednesday after doubts arose over the cuts it proposed.
Washington remains deadlocked as a deadline to increase the government’s borrowing authority looms on 2 August.
