My friend Noah Shachtman’s blog Danger Room has a huge scoop. It used to be that ex-GOP Rep. Curt Weldon (R-Penn.y, drunk off the Henny) was a bit eccentric. Now it’s looking more like he’s crossed the line into the gun trade.

Former congressman Curt Weldon is helping broker deals between Russian and Ukranian weapons suppliers and the Iraqi and Libyan governments as part of his new job with a private American defense consulting firm, Wired.com has learned.

Weldon, who is currently being investigated by the FBI over alleged corruption during his time in office, visited Libya in March to discuss a possible military deal, according to a letter describing the trip from Weldon to Defense Solutions CEO Timothy Ringgold. In May, Weldon, together with Ringgold and another company representative, traveled to Moscow to discuss working with Russia’s weapons-export agency on arms sales to the Middle East.

Both trips were part of the company’s effort to tap into the growing — and often legally murky — market for selling weapons from former Eastern Bloc countries to the Middle East and Afghanistan.

Here’s the potentially-felonious part:

U.S. government efforts to rapidly equip countries like Afghanistan and Iraq — which have largely Soviet-origin weapons — have created legal ambiguities and loopholes in export controls that didn’t exist in years past and given rise to a new class of arms trade middlemen. So, even though both Libya and the Russian arms export agency are on official U.S. blacklists, government officials and analysts involved in weapons sales say the rules have become unclear as the push to equip allies in the global war on terror has blazed new but uncertain legal ground.

Eagerly stepping into that virgin territory is Defense Solutions, a Pennsylvania-based company that is carving out a small but lucrative niche in a new international arms bazaar. The firm boasts as its advisors a number of influential Washington insiders, such as retired General Barry McCaffrey, the former White House drug czar.

Helping the firm make key connections is Curt Weldon, a former Republican congressman from Pennsylvania at the center of an FBI investigation into alleged conflicts of interest during his time in office. Weldon, now a key executive at Defense Solutions, is working with the company to set up these weapons deals.
