WASHINGTON — US Treasury Secretary Timothy Geithner might leave his job after the White House reaches a deal with Congress over raising the US debt ceiling, Bloomberg reported Thursday.

Geithner, one of the stalwarts of President Barack Obama's administration and a key architect of its policies during the economic crisis, has not reached a final decision on leaving, the agency said, citing unnamed sources familiar with the issue.

Geithner "has signaled to White House officials that he's considering leaving the administration," Bloomberg said.

His resignation would only come if and when a deal on hiking the $14.29 trillion debt cap happens, according to the report.

Obama and Geithner have both warned Republican opponents in Congress to raise the limit before August 2 to avert a default on US debt that could rock both the domestic economy and the global financial system.

White House officials offered no immediate comment on the report.

Geithner's departure, if it happens, would follow the already-announced departure of top White House economic advisor Austan Goolsbee.

Goolsbee is scheduled to leave in August.
