As a member of the House Oversight and Government Reform Committee, John Yarmuth apparently has a front-row seat to one of the most bitter clashes in the current congress.

The division stems from disagreements between chairman Darrell Issa (R-CA) and ranking Democrat Elijah Cummings (MD). We talked to Yarmuth about this when he was appointed to the committee.

Here’s an update from Politico:

Democrats say that Republicans are actively withholding committee documents. For example, Democrats want Republicans to fork over letters Issa solicited from trade associations on what the GOP dubs “harmful regulations.” Issa’s staff is reviewing and analyzing the information, and will make them available Feb. 11. That wasn’t good enough for Cummings and his staff, so they sent a letter to industry asking for information identical to what Issa requested.

While a lot of this seems like petty bureaucratic infighting among committee partisans, it could have a real affect on major committee investigations into the Obama administration, stimulus oversight and other areas Issa has targeted.
