Tim Scott declines to say whether he'd back the 2024 GOP presidential nominee if it's Trump

Republican Senator Tim Scott of South Carolina, who announced Wednesday he's testing the waters for a presidential bid, will not say whether he'd support former President Donald Trump in 2024 if he's the GOP nominee.  

Scott, who is forming a presidential exploratory committee, a precursor to running for president, twice declined to answer a question about supporting Trump in an interview with CBS News political correspondent Caitlin Huey-Burns in Iowa.

"If Donald Trump is the nominee for the Republican Party, would you support him?" Huey-Burns asked.
