The FBI's probe of U.S. Rep. Henry Cuellar reportedly appears to have something to do with his interest in Azerbaijan. ABC News says a federal grand jury probe has issued subpoenas seeking records from organizations with ties to the oil-rich former Soviet republic. That includes three Texas-based companies with ties to Cuellar's wife. Cuellar says the probe isn't interfering with his reelection campaign. He hasn't been charged with a crime.
