Florida - President Donald Trump may have threatened to transport illegal immigrants to so-called sanctuary cities to “make everybody crazy” and generate media attention, Republican U.S. Senator Rick Scott said on Sunday.

Trump said on Friday he was considering sending illegal immigrants to sanctuary cities, prompting U.S. mayors to accept such an offer as the battle over border security rages.

Sanctuary cities are local jurisdictions that generally give undocumented immigrants safe harbor by refusing to use their resources to help enforce federal immigration laws that could lead to deportations. Many such jurisdictions are Democratic strongholds.

Speaking to CNN’s “State of the Union,” Scott said he did not know if transporting immigrants to these jurisdictions was legal or illegal, adding: “I mean maybe he’s just saying this to make everybody crazy, make everybody talk about it on their shows.”

Scott, a former Florida governor who was elected to the U.S. Senate in November, has generally kept his distance from Trump and criticized him in the past over immigration policies and other issues.

Frustrated by rising numbers of undocumented immigrants arriving at the southern border and a failure to get Congress to fully fund a U.S.-Mexico border wall, Trump taunted Democrats by dangling the possibility of an influx of illegal immigrants into their communities.

“Due to the fact that Democrats are unwilling to change our very dangerous immigration laws, we are indeed, as reported, giving strong considerations to placing Illegal Immigrants in Sanctuary Cities only,” Trump wrote on Twitter. Read more at Reuters
