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 Wednesday, Paxton's former second-in-command, Jeff Mateer, testified that his former boss abused the power of his office to help a political donor. 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 last for weeks.
