Donald Trump will return to Phoenix next week, but campaign staffers now say he won't be delivering a speech outlining his immigration policy there.

Campaign officials had confirmed the Aug. 31 immigration speech in Phoenix earlier Wednesday. But Arizona campaign chair Brian Seitchik said later that the event will instead be a Republican unity rally. The campaign blamed a "staff error."

Trump has been working to soften the harsh tone on immigration that became a hallmark of his primary campaign. He had scheduled a speech on immigration in Colorado for Thursday but cancelled it.

Hillary Clinton is defending her family's charitable foundation and calling an Associated Press report about meetings involving donors "absurd," and "a lot of smoke, no fire."

Clinton says in an interview with CNN that the AP report "looked at a small portion of my time" as secretary of state and drew the conclusion that her meetings with Nobel Prize winners were connected to the foundation rather than their work as global leaders.

An AP report Tuesday found more than half of the non-government officials who met with Hillary Clinton while she was secretary of state gave money to the Clinton Foundation. Combined, the donors contributed as much as $156 million to the charity.

Donald Trump is returning to Phoenix to deliver a speech outlining his immigration policy as he works to soften the harsh tone that became a hallmark of his primary campaign.

The Republican presidential nominee plans to speak at the Hyatt Regency in downtown Phoenix Aug. 31.

Arizona Republican Party Chairman Robert Graham confirmed the event and that the speech would cover "policy." Two officials with knowledge of the Trump campaign's plans confirmed the topic was immigration. They weren't authorized to speak on the record about campaign plans.

Trump has recently been modifying his pledge to deport the 11 million immigrants in the United States illegally. Aides have suggested he'll back away from his deportation plan toward one closer to what many of his Republican rivals favored.
