Texas Attorney General Ken Paxton has joined 20 other Republican attorneys general Wednesday in a 14-page letter to the U.S. Senate condemning the impeachment of President Donald Trump.

Paxton and the AGs from Georgia, Florida, Alabama, South Carolina, Louisiana, Utah, Alaska, Arkansas, Indiana, Kansas, Kentucky, Mississippi, Missouri, Montana, Nebraska, Ohio, Oklahoma, South Dakota, Tennessee, and West Virginia called the articles of impeachment legally flawed and detailed their reasoning in what they called a “friend of the Senate” letter.
