Former President Trump has endorsed Vito Fossella, the scandal-scarred former congressman, in his bid to become Staten Island borough president.

“Vito Fossella will not let you down,” Trump promised in an email sent to supporters Saturday through his Save America PAC.

“He is strong, tough, loves our Country and truly loves the Great People of Staten Island — a powerful voice against crime and all other things going wrong in the city that we love,” Trump continued.

The former president waded into the uber-local race as Fossella came under fire for campaign finance filings that disclose less than $113 in spending — while blanketing the borough with pricey lawn signs and erecting a highway billboard alongside the Outerbridge Crossing.

Fossella, one of four Republicans vying for the GOP’s nomination in Tuesday’s borough presidential primary, left Congress in shame in 2009 in the wake of a second-family scandal that emerged after he was arrested for drunk driving.
