The return of in-person Republican and Democratic national conventions for the first time since 2016 provides the Secret Service with a daunting task, but Secret Service Director Kimberly Cheatle said there are no specific threats against either convention.

The Republican National Convention begins in one week in Milwaukee, with the Democratic National Committee five weeks later in Chicago. Cheatle, speaking on ABC News’s This Week on Sunday, said the Secret Service is considering the heightened political polarization in recent years when preparing for both conventions.
