Upping the Ante, Issa Says Obama Conspired With DOJ Congressman's letter escalates Fast & Furious battle By Evann Gastaldo, Newser Staff Posted Jun 26, 2012 9:05 AM CDT 97 comments Comments Rep.

(AP Photo/Susan Walsh) (Newser) – Darrell Issa is upping his attack on President Obama following the president's use of executive privilege in an attempt to bail out Eric Holder. A letter to Obama released today minces no words: "Either you or your most senior advisors were involved in managing Operation Fast & Furious and the fallout from it," it reads, "or, you are asserting a presidential power that you know to be unjustified solely for the purpose of further obstructing a congressional investigation." The White House has continued to insist it has not been working with the DOJ during the congressional investigation into the failed ATF gun-walking operation, but Issa says Obama's use of executive privilege raises doubts about that assertion. Politico notes that the letter probably won't force Obama to do anything, but will definitely get attention. This week is a particularly tense one for the White House: It's very possible the House's decision on whether to hold Holder in contempt will come on the same day as the Supreme Court decision on ObamaCare. Meanwhile, Democrats are looking to spin the contempt motion—as an assault on minority rights that could possibly suppress voters, seeing as the DOJ is currently fighting against voter ID laws. Al Sharpton and a number of other civil rights leaders will hold a press conference on the issue today. "I’m not saying that this is because Holder is black, and I’m not calling [Republicans] racists," Sharpton tells The Hill. "I’m saying what they’re doing has a racial effect, and that’s what we’re going to talk about."
