Sen. John Cornyn (R-TX) said he hasn’t heard any Republicans label President Donald Trump, 79, “too old” in response to primary challenger Rep. Wesley Hunt‘s (R-TX) call for the “next generation.”

Hunt and Texas Attorney General Ken Paxton are challenging Cornyn in the Texas Senate primary as the incumbent seeks a fifth six-year term. Hunt, 44, said last week that “it’s time for the next generation of leadership to step up,” taking a shot at Cornyn, 74, by saying the Senate is “not a retirement community.”
