The FBI is confirming that they were at the Laredo home of Democratic U.S. Rep. Henry Cuellar on Wednesday. Agents were reportedly taking cases and other items from Cuellar's home, and were also at a downtown building Cuellar owns that reportedly houses his campaign office. An FBI spokesperson says the agents were conducting part of a court-authorized investigation, but she didn't say what they were looking for. Cuellar's office issued a statement on Wednesday saying he will fully cooperate.
