Presidential candidates meet and greet voters at Iowa State Fair

DES MOINES, IA -- Here is the latest from the presidential candidates as they meet and greet voters at the Iowa State Fair (all times are local):

11:55 a.m.

Democratic presidential candidate Hillary Rodham Clinton is standing firm that she never sent or received emails on her homebrew email server that were marked classified.

Clinton tells reporters at the Iowa State Fair on Saturday she was going to let the inquiry into her email use go forward. Clinton turned the server over to the FBI recently to investigate the security of her email setup.

Thousands of pages of her emails publicly released in recent months show Clinton did receive messages later marked classified, including some that contained material regarding the production and dissemination of U.S. intelligence.

Clinton's use of a homemade server during her time as secretary of state has dogged her campaign. She blamed her Republican challengers and GOP House members on Saturday for turning the affair into a partisan issue.

10:59 a.m.

Republican presidential front-runner Donald Trump is set for a rock-star's entrance to the fair, landing in a helicopter in athletic fields just over a mile from the fairgrounds. He plans to visit the famed butter cow, but the Des Moines Register's political soapbox isn't on his itinerary.

Trump is feuding with the newspaper after it published an editorial last month calling for the real estate mogul to end his bid for the White House. The Trump campaign, in turn, denied credentials to the newspaper's reporter to cover his campaign.

Trump descends on the Iowa summer festival as the leading Republican candidate. His standing in the leadoff caucus state has remained strong despite a recent dust-up with Fox News host Megyn Kelly and ongoing criticism over his comments about Mexican immigrants.

Trump has drawn enthusiastic response for promising to be a smart president who makes great deals. So far he has not released any specific policy proposals.

9:30 a.m.

The Democratic and Republican front-runners are among the presidential candidates courting voters Saturday at the Iowa State Fair, but Hillary Rodham Clinton and Donald Trump are unlikely to cross paths.

The early arrival at the fairgrounds was Democrat Lincoln Chafee, who strolled the main pathway greeting voters before 9 a.m.

The former Rhode Island governor says when he takes the soapbox in the afternoon he'll extoll his executive experience and his plans for the future. He also says he hopes to check out some of the livestock. But when asked what fair food he may try, he hedged.

Chafee says, "You've got to be careful at these fairs."

Also expected at the fair Saturday are Vermont Sen. Bernie Sanders and former Pennsylvania Senator Rick Santorum.
