Acting Homeland Security Secretary Kevin McAleenan, also on Sunday, acknowledged that federal officials did initially alert local leaders of the possibility that migrants would be flown to two South Florida counties.
But Trump appeared to blame the media for "false reporting."
"There are no plans to send migrants to northern or Coastal Border facilities, including Florida," Trump wrote on Twitter. "...Our country is FULL, will not, and cannot, take you in!"
The office of Florida Gov. Ron DeSantis also said Sunday that Trump told him he didn't approve and wouldn't authorize to fly the immigrants.
