Trump: Americans 'are demanding that Sanctuary Cities be GONE'

President Trump in early morning tweets on Sunday said Americans "are demanding that Sanctuary Cities be GONE."

Trump, citing Fox News, initially noted that Florida Gov. Ron DeSantis (R) "just signed Bill banning Sanctuary Cities in State, & forcing all law enforcement agencies to cooperate with Federal Immigration authorities."

"More and more states want to do this but their governors and leaders don't have the courage to do so," he said in a follow-up tweet.

"The politics will soon mandate, however, because people from California, & all over the land, are demanding that Sanctuary Cities be GONE," he added. "No illegals, Drugs or Trafficking!"

DeSantis signed the legislation Friday.

The Associated Press reported that members of the crowd around DeSantis during the signing ceremony wore red "Make America Great Again" hats and cheered in support of the bill and at the mention of Trump.

The controversial bill prohibits "sanctuary" policies that protect undocumented immigrants from deportation and requires state and local law enforcement agencies to work with federal immigration officials to identify immigrants who don't have legal status.

The law also mandates that Florida law enforcement officers detain someone if there's probable cause that the person is "removable" under federal immigration laws, the Miami Herald reported, adding that there are no sanctuary cities in the state. The newspaper also noted that legal challenges to the legislation are expected.

Critics say the measure is unconstitutional and violates the Fourth Amendment.

"The legislation inhumanely separates families, tearing apart parents and their children, while doing nothing to address legitimate public safety concerns," Scott McCoy, senior policy counsel for the Southern Poverty Law Center Action Fund, wrote in a statement. "This can have traumatic long-term effects on our youth and our communities."
