Citing §6103(f) of the Internal Revenue Code, Democrats say there is no wiggle room for the Secretary of Treasury or the IRS - that the feds "shall furnish" the documents to the House Ways and Means Committee.

"Enacted in 1924, in the wake of Congressional attempts to investigate agency wrongdoing in the Teapot Dome corruption scandal, Section 6103(f) was intended to provide the Committee with unfettered access to tax return information necessary to carry out its broad mandate to oversee Treasury, the IRS, and the Nation's tax laws," the committee's lawsuit states.
