Florida Gov. Ron DeSantis has promised to veto a sweeping immigration bill. It's the latest escalation in a statehouse showdown between DeSantis' office and the Republican leaders, who have sparred over whose proposals would best carry out President Donald Trump's immigration crackdown.

Florida Republican lawmakers defied Gov. Ron DeSantis' call for a special session on immigration by tossing out the governor's proposals and convening their own special legislative session to carry out President Donald Trump's federal immigration orders.
