Jack Lew Under Fire for Ignoring Medicare Warnings

The law requires a response to a formal heads-up

Treasury secretary nominee Jack Lew is coming under fire from Senate Republicans who question whether he violated federal law by declining to respond to dire warnings from the group that oversees Medicare.

Eight Senate Republicans voiced their complaints in a letter Monday to the White House budget office, which Lew ran before being promoted to President Obama's chief of staff. The criticism comes as the president's most controversial Cabinet nominees line up for confirmation hearings before Congress.
