Baucus's office said in Tuesday's meeting with Lew, the current White House chief of staff, he "discussed the many fiscal challenges facing our nation, including the need for serious action to address the debt."
Democrats believe that Lew, whom President Obama officially nominated on Monday, will get confirmed. The current Treasury secretary, Timothy Geithner, is scheduled to exit at the end of the week.
Some Republicans have said Lew previously gave misleading testimony about a White House budget, or have questioned his role in past fiscal negotiations.
