Florida Gov. Ron DeSantis is ending his turbulent presidential campaign and will endorse former President Donald Trump.

DeSantis announced he’s ending his campaign in a video.

DeSantis’ run came to a halt following a dispiriting second-place finish in Iowa, a state where he and allies poured millions into an aggressive get-out-the-vote effort that featured the governor visiting all 99 counties. He spent week after week in the state instead of establishing a presence in other early voting states like New Hampshire and South Carolina.

DeSantis had initially been considered a formidable challenger to former President Donald Trump. But DeSantis was unable to gain traction in the primary, with Trump instead steadily consolidating support and rising in the polls before a dominant win in Iowa.
