WASHINGTON (Reuters) - U.S. Treasury Secretary Steven Mnuchin on Friday urged Congress to increase the nation’s debt ceiling before its summer recess.

In a letter to House Speaker Nancy Pelosi, Mnuchin said that while there was “reasonable uncertainty” in projecting government cash flows, updated projections showed “there is a scenario in which we run out of cash in early September, before Congress reconvenes.”

“As such, I request that Congress increase the debt ceiling before Congress leaves for summer recess,” he said.
