"Senator John Thune Endorses Donald Trump for 2024 Presidential Run"

Sen. John Thune, the No. 2 Republican in the Senate, has endorsed former president Donald Trump in the GOP presidential primary, despite previous animosity between the two. Thune's endorsement comes after Trump's victory over Nikki Haley in South Carolina's primary, and he expressed his support for Trump's campaign and intention to work towards a Republican majority in the Senate. Thune's decision adds pressure to Senate Minority Leader Mitch McConnell, who has not endorsed Trump and has stayed out of the GOP's presidential nominating contest.
