The man charged with killing the reputed boss of the Gambino crime family has appeared in court with 'MAGA forever' scrawled on his hands.

Anthony Comello, 24, was arrested on Saturday in New Jersey in the shooting death of Francesco Cali last week in front of his Staten Island home.

While waiting for a hearing to begin in Toms River, New Jersey, on Monday in which he agreed to be extradited to New York, Comello held up his left hand.

He had the pro-Donald Trump slogans scribbled across his palms around a large circle.

In addition to the 'Make America Great Again' slogan, Comello also had 'United We Stand MAGA' written in blue ink and 'Patriots In Charge.'

Anthony Comello, 24, faced a New Jersey court on Monday with 'MAGA forever' scrawled on his hands. He agreed to be extradited to New York to faces charges in the shooting death of Gambino boss Francesco Cali

Comello's lawyer, Brian Neary, would not discuss the writing on his client's hand.

He also wouldn't say whether Comello maintains his innocence. When asked by reporters after the hearing what was on Comello's hand, Neary replied: 'Handcuffs.'

Comello sat with a slight smile in the jury box of the courtroom on Monday afternoon as dozens of reporters and photographers filed into the room. When they were in place, Comello held up his left hand to display the writings as the click and whirr of camera lenses filled the room with sound.

During the hearing, a bored-looking Comello did not speak other than to say, 'Yes, sir' to the judge as he answered several procedural questions.

Comello, who works odd construction jobs, will now be extradited from New Jersey to New York to face charges in the shooting death of the 53-year-old mob boss.

Cali, a native of Sicily, was shot 10 times outside his home last Wednesday. Police believe the gunman crashed his truck into Cali's home to lure him outside.

Police wouldn't confirm the motive but sources have said Comello's dispute with Cali was because the mob boss refused to let him date his niece.

Comello has been described as 'a complete nut' and as a 'conspiracy theory type', various sources say.

In addition to the 'Make America Great Again' slogan, Comello also had 'United We Stand MAGA' written in blue ink and 'Patriots In Charge'

Comello was taken into custody after police found a finger print on the license plate of Cali's silver Escalade, which had fallen from the vehicle when the gunman crashed into his car.

Comello was arrested on Saturday in New Jersey in connection with the murder of Gambino crime boss Francesco 'Franky Boy' Cali

Surveillance video that captured the murder showed Cali heading outside his home on March 13 after a blue pickup truck reversed forcefully in his parked car.

The footage - which had to be obtained by a warrant - shows Cali and the man engaging in a conversation, before shaking hands.

The man then passes Cali a licence plate that had fallen off his Escalade.

But as the crime boss turned his back to place the plate in the trunk of his car, the gunman - now allegedly believed to be Comello - took out a 9mm pistol and opened fire.

Cali tried to hide from the gunfire underneath his car, which initially led investigators to believe he'd been run over in the hit.

Investigators with the NYPD were forced to obtain a warrant to review the surveillance video after the victim's relatives' were allegedly unwillling to comply with the probe.

Federal prosecutors referred to Cali in court filings in recent years as the underboss of the Mafia's Gambino family, once one of the most powerful crime organizations in the country. News accounts since 2015 said he had ascended to the top spot.

Cali's only mob-related criminal conviction came a decade ago, when he pleaded guilty in an extortion scheme involving a failed attempt to build a NASCAR track on Staten Island. He was sentenced to 16 months behind bars and was released in 2009.

The last Mafia boss to be rubbed out in New York City was Gambino don 'Big Paul' Castellano, who was assassinated while getting out of a black limousine outside a high-end Manhattan steakhouse in 1985.

John 'Dapper Don' Gotti arranged Castellano's assassination.

Police were previously thought to be considering Gene Gotti, John's younger brother, as a suspect in Cali's murder. Gene was released from prison after 29 years just six-months ago.
