Ken Paxton and James Talarico campaigned in Texas as a new poll shows the Democratic candidate with a narrow lead in the U.S. Senate race.

There is growing concern in GOP ranks that Republican Ken Paxton isn't working hard enough to beat Democrat James Talarico in the state's U.S. Senate race, and it's spilling out onto national TV.

Ken Paxton says he's confident Texans will reject James Talarico once they learn about his record on border security, energy and social issues.
