Former Trump primary rival Haley in Republican convention spotlight on day after JD Vance named running mate

MILWAUKEE- One day after Donald Trump was formally nominated as the GOP's 2024 presidential nominee and named Sen. JD Vance of Ohio as his running mate, Trump's final rival during the presidential primaries takes center stage at the Republican National Convention.

And as part of that push for unity, Haley was invited to speak at the convention.
