Politicization of DoJ investigations?

The WSJ is seeing it, too.

As midterm elections approached last November, federal investigators in Arizona faced unexpected obstacles in getting needed Justice Department approvals to advance a corruption investigation of Republican Rep. Rick Renzi, people close to the case said.

The delays, which postponed key approvals in the case until after the election, raise new questions about whether Attorney General Alberto Gonzales or other officials may have weighed political issues in some investigations. The Arizona U.S. attorney then overseeing the case, Paul Charlton, was told he was being fired in December, one of eight federal prosecutors dismissed in the past year.
