Lieberman, Collins, Grassley express 'serious concern' about ITC's IG

Scored a minor scoop today from Capitol Hill:

Three senators, including Homeland Security Committee Chairman Joe Lieberman, have sent a letter to Shara L. Aranoff, chairwoman of the International Trade Commission, expressing "serious concerns" about the contractual terms under which the ITC's inspector general is hired.
The letter, signed by Lieberman, Sen. Susan Collins of Maine -- the committee's ranking Republican -- and Sen. Charles Grassley (R-Iowa), complained of the ITC's unusual practice of hiring the agency's IG under a six-month contract, which the senators suggest may undermine the watchdog's independence.

Read the whole thing. What is significant is that this is the first evidence that Lieberman's committee is willing to cooperate with Grassley, who has been bulldogging IG-Gate for nearly two months.
