1. Letter from federal lawyers implies Trump case against congestion pricing is weak

An internal legal memo that the U.S. attorney's office says was filed by mistake reveals that federal lawyers believe it will be difficult for the government to win its case against congestion pricing.

The letter, dated April 11, seems to have been accidentally uploaded to PACER, the electronic filing system for the federal courts, by a U.S. attorney defending Transportation Secretary Sean Duffy in the suit brought by the MTA against him.

2. Staten Island City Council candidates to debate on NY1 ahead of special election

3. Judge bars Trump from denying federal funds to ‘sanctuary’ cities that limit immigration cooperation

A federal judge in California today barred the Trump administration from denying or conditioning the use of federal funds to “sanctuary” jurisdictions, saying that portions of President Donald Trump's executive orders were unconstitutional.

U.S. District Judge William Orrick issued the injunction sought by San Francisco and more than a dozen other municipalities that limit cooperation with federal immigration efforts.

4. Man charged with arson after authorities say he sparked N.J. blaze

A man set wooden pallets on fire and failed to properly put them out in New Jersey's Pine Barrens, sparking a quick-moving wildfire with smoke affecting the air quality in the New York City area, authorities said today.

Ocean County Prosecutor Bradley Billhimer and Department of Environmental Protection Commissioner Shawn LaTourette said the Waretown man faces aggravated arson and arson charges in the southern New Jersey wildfire, which authorities said this morning grew to more than 23 square miles.

5. Health commissioner warns of vaccine confusion amid measles outbreak

A growing measles outbreak that began in West Texas is now spreading across the country — with the CDC reporting 800 cases across 24 states, including New York. Nationwide, three people have died, including two children.

New York State Health Commissioner James McDonald joined “Mornings On 1” today, stressing the importance of the MMR vaccine and calling out misinformation.

6. Vatican keeps St. Peter's open all night for public viewing of Pope Francis due to strong turnout

So many mourners lined up to see Pope Francis lying in state in a simple wooden coffin inside St. Peter's Basilica that the Vatican kept the doors open all night due to higher-than-expected turnout, closing the basilica for just an hour this morning for cleaning.

The basilica is bathed in a hushed silence as mourners from across the globe make a slow, shuffling procession up the main aisle to pay their last respects to Francis, who died Monday after a stroke.
