New York is moving full steam ahead with its congestion pricing plan to further toll drivers entering lower Manhattan.

And after months of protests from state leaders, New Jersey is pushing back in court.

The Murphy administration today sued the federal government, arguing it gave an uncritical rubber stamp approval to the plan.

The goal of congestion pricing is to reduce traffic, slash pollution and boost public safety in the city.

But New Jersey officials say they fear it will only push financial and environmental burdens onto this side of the Hudson.

Murphy announced the lawsuit this morning, and that's not all he did to try and stick it to New York.

Senior correspondent Brenda Flanagan reports.

We are suing to block New York's ill conceived congestion pricing plan.

Governor Murphy's throwing a Hail Mary legal challenge, attempting to outmaneuver New York's plans to implement congestion pricing south of 60th Street in Manhattan, a plan that would raise $1,000,000,000 for the MTA but charge New Jersey commuters up to 23 bucks for a border crossing.

Murphy is suing the Federal Highway Administration and U.S. Department of Transportation.

We're not going to allow this poorly designed proposal to be fast tracked when the law doesn't allow it.

At its heart, this is a matter of New Jerseyans being treated fairly, and we will fight like tooth and nail to ensure that is the case.

The lawsuit slams federal officials, quote, misguided decision to let the plan proceed without conducting a complete environmental impact study.

It charges heavy truck traffic will pile up at the George Washington Bridge trying to avoid paying congestion pricing fees on top of tunnel tolls.

Trucks will be backed up here in North Jersey as far as the eye can see, blowing cancer, causing pollution into the lungs of children in our communities.

The MTA chairman should come to Fort Lee and look.

Mayor Sokolich in the eye and tell him why it's okay to give cancer to the children in our communities.

Opponents complain the MTA set aside $130 million to mitigate traffic fumes for kids in the Bronx, but not a nickel for Jersey children.

And with New York unlikely to offer exemptions or discounts for Jersey commuters, as politicians here fumed.

We are not.

The MTA is a team, period.

And if they don't know that by now, they're going to learn it.

New York must provide full toll credits for our commuters, and they must exempt our busses.

New York's congestion tax plan, in my view, is a brazen money grab.

It's highway robbery.

Under no circumstances should the state of New York and its MTA make up its budget shortfall by squeezing every dollar from the neighbors across the river.

Meanwhile, advocates who support congestion pricing because it will reduce traffic congestion and vehicle emissions downtown gathered outside the governor's news conference.

They called his lawsuit anti-environment and hypocritical.

For someone who's a champion for the climate.

New Jersey Transit is underfunded.

New Jersey Transit has no dedicated state funding.

Congestion pricing is dedicated funding for the MTA.

We want Governor Murphy to address his own hypocrisy and look for ways in New Jersey to fund New Jersey transit because riders aren't getting where they need to go.

This lawsuit is just the biggest shot in a broadside against New York's congestion pricing plan.

Jersey is also slapping back with new rules designed to keep tax dollars on the side of the Hudson.

This is now the law of the land.

Under the new law, Jersey will collect taxes from New York residents who work at home for New Jersey companies.

New Jersey residents could get tax credits if they successfully file lawsuits against states like New York that tax their income.

And New Jersey will pay.

New York companies that opened offices in Jersey so remote workers here won't have to pay New York income tax.

Meanwhile, Governor Murphy's not asking for a temporary injunction to block congestion pricing.

Even though the MTA is already assembling license plate readers on the plan perimeter.

I hope there's a deal.

But the step today is let's make sure the feds do what they should have done, which is do a full bore assessment.
