The impeachment trial of Texas Attorney General Ken Paxton continues today in Austin. Paxton has pleaded not guilty to the 16 charges against him. On Monday, Mark Penley, who ran the office's criminal division, said he and the other whistleblowers were fired when they refused to help a Paxton campaign donor who believed the federal government was after him. The Texas House impeached Paxton in May, and the Republican-led state Senate will decide whether to remove him from office. The trial is expected to wrap up on Friday.
