SIOUX CENTER, Iowa (AP) Stunning new revelations about former President Donald Trump s fight to overturn the 2020 election have exposed growing political vulnerabilities just as he eyes another presidential bid.

A former White House aide this week described Trump as an unhinged leader with no regard for the safety of elected officials in either party as he clung to power on Jan. 6, 2021 . The testimony from the congressional panel investigating the Capitol attack provided a roadmap for prosecutors to potentially charge Trump with a crime, some legal experts say.

Republican voters and Trumps would-be rivals in the 2024 presidential race took notice.

Here in Iowa, the state expected to host the first presidential nominating contest in roughly 18 months, several voters signaled Thursday that they were open to another presidential candidate even if Trump were to run again. At the same time, some conservative media outlets issued scathing rebukes of the former president. Aides for multiple GOP presidential prospects also indicated, publicly and privately, that they felt increasingly emboldened to challenge Trump in 2024 following the explosive new testimony.

Nikki Haley, Trumps ambassador to the United Nations, drew roughly 350 conservative activists to a congressional fundraising barbecue on Thursday in Sioux County, where Trump won 82% of the vote in 2020.

And there was ample evidence of Trump fatigue. Interviews with a dozen attendees revealed strong interest in a 2024 alternative, even if Trump is on the ballot.

Youd be hard-pressed to find people in this area who support the idea that people arent looking for someone else, said Dave Van Wyk, a transportation company owner. To presume that conservative America is 100% behind Donald Trump is simply not the case.

For some Republican voters, that was the feeling even before this weeks stunning new testimony.

Former White House staffer Cassidy Hutchinson on Tuesday offered previously unknown details about the extent of Trumps rage in his final weeks of office, his awareness that some supporters had brought weapons to the city on Jan. 6 and his ambivalence as rioters later laid siege to the Capitol.
