Former acting Director of National Intelligence Ric Grenell is reportedly slated to address the Westside Conservative Club in Urbandale, Iowa, and the Dallas County GOP this week. The two appearances are nearly certain to spur speculation the Trump administration official is angling to become Trump’s running mate in 2024.

The Hill reports:

The appearances are likely to stir further speculation that Grenell may be angling for the role of Trump’s running mate in 2024 should the former president mount another campaign for the White House.

Iowa is the first state to vote in presidential nominating contests, and prospective presidential and vice presidential contenders tend to flock there months, or even years, before making their ambitions public.

Grenell, who isn’t seen as a potential presidential contender himself, has a lengthy history of working for Trump. He served as the former president’s ambassador to Germany for two years, as well as the acting director of national intelligence and as a special presidential envoy for Serbia and Kosovo Peace Negotiations.

Grenell has also stayed active in Republican politics since leaving the Trump administration. He campaigned for Nevada Republican Senate nominee Adam Laxalt days before the state’s June 14 primary.

Trump has remained tight-lipped over who he would consider as a running mate if he ultimately decides to run in 2024. Some have speculated House GOP Conference chair Elise Stefanik or Florida Governor Ron DeSantis could be potential picks for vice president.
