Hatch expressed doubt about the deadline, which has been widely accepted in negotiations as the point in time at which the U.S. would default on its financial obligations if the ceiling is not lifted. 

"Maybe the date is July 29,” said Hatch. “I don't know … Maybe the date is Aug. 15. I don't know … the American people don't know. And this is unacceptable." 

Hatch said he had written a letter to the Financial Stability Oversight Council demanding cash-flow figures by 5 p.m. on Thursday but that his requests were left unanswered.

"I'm a little shocked that I’m not getting this kind of cooperation," said Hatch. "[I] have received no reply about Treasury cash flows and liquid assets. Nothing. Radio silence."
