New York: Former US President Donald Trump is set to fly from Florida to New York City on Monday, ahead of his scheduled arraignment related to hush money paid to a porn star before the 2016 election, as security tightens in Manhattan.

Trump, the first former US president to face criminal charges, is due to be arraigned, fingerprinted and photographed at the downtown Manhattan courthouse on Tuesday. His lawyers have said he will enter a plea of not guilty.

New York police during the weekend began erecting barricades along the edge of the sidewalks around Trump Tower and the Manhattan Criminal Court building downtown, and some other courtrooms will be cleared.

Demonstrations are expected at those sites and police vowed to be prepared. “Officers have been placed on alert and the department remains ready to respond as needed and will ensure everyone is able to peacefully exercise their rights,” the New York Police Department said in a statement.

Other courtrooms on the courthouse’s higher floors will be shut down ahead of the arraignment as part of the security precautions, a court official said.

US Representative Marjorie Taylor Greene tweeted an invitation on Sunday to join her at a protest near the courthouse on Tuesday, saying “They’re not coming after President Trump, they’re coming after us, he’s just in their way.”
