Lew to testify on Capitol Hill on 2014 budget

"This hearing will provide both the committee an opportunity to review the president’s tax proposals and Treasury Secretary Lew the opportunity to describe how the administration intends to work with the committee and Congress to pass and enact comprehensive tax reform," said panel Chairman Dave Camp (R-Mich.). 

Lew will be joined at the Capitol by Jeff Zients, the former deputy at the OMB, who will testify on Thursday before the Senate Budget panel.

The hearings also come a day after Obama is set to have dinner with a dozen Republicans. Georgia Sen.

The location is being chosen by the White House and is unknown. 

Camp reiterated his commitment to comprehensive tax reform that "eliminates tax loopholes, simplifies the code and lowers rates." 

Obama's budget plan is expected to include a clearer picture on entitlement cuts, as well as less tax revenue than the nearly $1 trillion in the Senate Democrats' blueprint. 

Congressional Republicans have been critical of the White House's inability to meet budget deadlines. 

But the Obama administration maintains that uncertainty of taxes and spending made it difficult to produce a budget.
