The head of the Tarrant County Republican Party is calling for Republican congressman Joe Barton to step down by the end of the year.
Barton apologized but said he will not resign for the scandal involving sexting photos of him that were posted on Twitter.
Tarrant County Party Chair Tim O'Hare said Tuesday he hopes Barton will place his constituents "above his personal desires to make way for a candidate who better embodies our values and who will ensure Congressional District 6 remains in Republican hands.
Barton now has at least one primary challenger, Jake Ellzey, a retired veteran in Midlothian who filed his paperwork Tuesday.
Most of District 6 covers Ellis and Navarro counties, but it also includes Arlington. Barton is seeking his 18th term in congress in 2018.
