DES MOINES, Iowa (AP) — The Latest on the 2016 race for president on the day of the country’s leadoff Iowa caucuses (all local times):

7:31 a.m.

Former Alaska Gov. Sarah Palin says she has no regrets having endorsed billionaire Donald Trump for president over his rival Ted Cruz, who she endorsed during his run for a seat in the U.S. Senate.

Speaking to NBC’s Today on the morning of the Iowa caucuses Monday, Palin said her support “added some momentum” to Cruz’s campaign and as the senator from Texas, he has gone on to fight for the American people.

“I want to keep him in the Senate and I want Donald Trump to be our president,” she said.

Palin also defended comments she made at one of Trump’s rallies when she blamed her son’s behavior on President Barack Obama for not doing more to help veterans suffering from post-traumatic stress syndrome.

Palin insisted that America needs a new president who she says will not “kowtow, allow the enemy to be poking at us.”

7:09 a.m.

Presidential candidates vying for their party nominations are toning down their attacks against rivals opting instead for messages of reflection on the morning of the country’s leadoff Iowa caucuses.

Speaking to NBC’s Today on Monday, billionaire Donald Trump declined to predict the outcome of the caucuses, noting that fellow Republican Sen. Ted Cruz is “a talented guy.”

On ABC’s Good Morning America, Trump is admitting: “You have to be a little bit nervous,”

Florida Sen. Marco Rubio also praised the drive of rival Cruz, with whom he’s repeatedly clashed on a range of issues, saying Cruz “has a very strong ground game.”

Democratic hopeful Hillary Clinton praised her campaign staff and said that rival Sen. Bernie Sanders has run the campaign he wants to run, noting, simply, “we have differences.”
