Trump still leads GOP polls in Iowa, but some voters grow weary

Former President Donald Trump's latest indictment on Monday fell right in the middle of an important political event: the Iowa State Fair. It's a tradition for presidential candidates to visit the fair and talk to voters ahead of Iowa's first-in-the-nation caucuses.

Trump attended the state fair on Saturday, drawing thousands of supporters. 

"The fair is huge and it's a really great opportunity for the presidential candidates to come out and really test the waters," said Iowa's junior GOP Sen. Joni Ernst.
