Some Republicans Will Take Center Stage at the Democratic Convention

The Democratic National Convention is expected to feature speeches from at least three Republicans, with a Republican hosting the convention’s second night, as Vice President Kamala Harris’s campaign seeks to highlight opposition to Donald J. Trump from within his own party.

Former Representative Adam Kinzinger of Illinois, who swept into Congress as part of the Tea Party wave of 2010 and then became one of the most vocal Republican opponents of Mr. Trump, then the president, after the Jan. 6, 2021, attack on the U.S. Capitol, will speak later in the week, according to a Republicans for Harris campaign official.

Ana Navarro, a Republican co-host of the “The View” on ABC who has criticized Mr. Trump for years, will host the convention’s prime-time events on Tuesday, according to the Democratic National Convention Committee.

And Rich Logis, a former pro-Trump pundit, will address the convention in a taped speech on Monday night, according to the Harris campaign. More Republican speakers will be announced on Tuesday, according to the convention committee.

Geoff Duncan, a Republican who was the lieutenant governor of Georgia when Mr. Trump sought to overturn the 2020 election result there, said in a phone call on Monday that he would also be in Chicago for the convention, but declined to say if he would deliver an address.

Mr. Logis, a co-chairman of Republicans for Harris in Florida, volunteered for Mr. Trump’s 2016 campaign. But he said he ultimately broke with Mr. Trump over his managing of the Covid-19 pandemic, the Jan. 6 attack and Republicans’ opposition to gun control.
