New York City Mayor Bill de Blasio jumped into the 2020 race on Thursday and immediately took a page out of President Trump's playbook.

De Blasio spoke with Good Morning America for his first televised interview after his 2020 announcement. The appearance may have only been a few minutes long, but the mayor still managed to squeeze in two usages of his rhyming nickname for the president.

"Donald Trump is playing a big con on America," de Blasio said. "I call him Con Don. Every New Yorker knows he's a con artist."

A few minutes later, de Blasio repeated the nickname for Trump while arguing the president has "conned us into thinking he's on the side of the working people when he's really on the side of the one percent."

Trump has yet to respond with his own nickname for de Blasio, although he tweeted on Thursday morning that de Blasio is "considered the worst mayor in the U.S." and "NYC HATES HIM!" Trump apparently wasn't up on the latest developments, though, considering he wrote that de Blasio "will supposedly be making an announcement" even though that announcement came about two hours earlier.

Other topics covered in de Blasio's Good Morning America interview included a recent Quinnipiac poll in which 76 percent of New York City voters said they didn't want de Blasio to run, which the mayor shrugged off by saying that "the poll that actually matters is the election." Brendan Morrow

The Saudi gunman who killed three people on Friday at Naval Air Station Pensacola in Florida went on Twitter before the shooting and accused the United States of being anti-Muslim, a U.S. official told The Associated Press on Sunday.

Saudi Royal Air Force 2nd Lt. Mohammad Saeed Alshamrani also apparently tweeted his anger over U.S. support of Israel. The FBI confirmed it is operating on the assumption the shooting was an act of terror, with investigators working to determine whether Alshamrani, 21, acted alone or with others. Alshamrani was in the U.S. for flight training, and was killed by a sheriff’s deputy during the attack.

The official also told AP investigators believe Alshamrani went to New York City a few days before the shooting, and they are trying to figure out the purpose of his trip. A second U.S. official told AP on Saturday Alshamrani hosted a dinner party prior to the attack, where he and three others watched videos of mass shootings.

Rachel J. Rojas, the special agent in charge of the FBI’s office in Jacksonville, said a Glock 9 mm weapon that had been legally purchased in Florida was used to carry out the shooting. In response, Florida Gov. Ron DeSantis (R) said he is against a "federal loophole" that lets foreigners purchase guns in the United States, and while he supports the Second Amendment, it "does not apply to Saudi Arabians."

Caroll Spinney, the actor and puppeteer who made Big Bird and Oscar the Grouch come alive on Sesame Street, died Sunday. He was 85.

The Sesame Workshop said Spinney, who died at his home in Connecticut, lived with dystonia for many years. Spinney began working on Sesame Street in its earliest days in 1969, before retiring in 2018.

As Big Bird, Spinney traveled around the world, conducted symphony orchestras, danced with the Rockettes, received a star on the Hollywood Walk of Fame, and was named a Living Legend by the Library of Congress.

In a statement, Sesame Workshop said Spinney's "enormous talent and outsized heart were perfectly suited to playing the larger-than-life yellow bird who brought joy to generations of children and countless fans of all ages around the world, and his loveably cantankerous grouch gave us all permission to be cranky once in a while."

The shooting — which is now being considered an act of terrorism — that resulted in three deaths at Naval Air Station Pensacola in Pensacola, Florida, on Friday has placed the United States' relationship with Saudi Arabia under a microscope.

The suspected shooter, identified as Saudi Royal Air Force 2nd Lt. Mohammad Saeed Alshamrani, was an aviation student at the base. The killing has led some people to question whether the partnership should continue, especially considering there have long been doubts about the alliance for a variety of reasons, most notably accusations of human rights abuses in Yemen and the murder of Saudi journalist Jamal Khashoggi.

But President Trump seems committed to U.S. policy toward Saudi Arabia, especially as his administration remains wary of Iran's influence in the Middle East. Trump said he spoke with Saudi Crown Prince Mohammad bin Salman after the shooting, who offered his condolences to family and friends of the deceased. There didn't, however, seem to be much in the way of rethinking the alliance.

That doesn't mean others haven't. Sen. Cory Booker (D-N.J.), who is aiming to challenge Trump as the next Democratic nominee, called the U.S. partnership with Saudi Arabia "unacceptable."

Rep. Matt Gaetz (R-Fla.), a supporter of Trump, said he was assured by Saudi Ambassador to the U.S. Princess Reema bint Bandar Al Saud that Saudi Arabia would not interfere with the investigation into the matter, unless requested. But he still said that Friday's shooting "has to inform" the U.S.-Saudi relationship. Tim O'Donnell

NBC's Chuck Todd really isn't sure why Sen. Ted Cruz (R-Texas), of all people, isn't more skeptical of President Trump.

Cruz, in an appearance on Sunday's edition of Meet the Press, said he still believes Ukraine interfered in the 2016 presidential election, which has become a major talking point among Republicans defending Trump during the impeachment inquiry that was spurred, in part, by Trump asking the Ukrainian government to investigate the claim.

As he did last week, when Sen. John Kennedy (R-La.) expressed a similar opinion, Todd seemed like he couldn't quite grasp what he was hearing. He then asked Cruz why he's so trusting of Trump considering he dealt with the president's attempts to manipulate a narrative about someone firsthand during the Republican primary battles in 2015 and 2016, including Trump's threat to "spill the beans" about Cruz's wife. The senator wasn't thrilled Todd brought that up, but he didn't backtrack on his comments about Ukraine.

Todd, for his part, wasn't buying Cruz's argument that Ukraine officials criticizing Trump during the election amounted to interference. The NBC host said Cruz, in comparing Ukraine's role in the elections to Russia, was basically comparing a pickpocket to Bernie Madoff. Tim O'Donnell

Only four weeks remain in the 2019 NFL regular season, and Sunday's slate of games is a doozy.

It'll be a particularly telling week for the AFC East, where the New England Patriots might actually have a real challenger for the division crown for the first time in what seems like forever – and people are excited.

New England, behind quarterback Tom Brady and head coach Bill Belichik, has won the last 10 division titles, but the upstart 9-3 Buffalo Bills, who were mostly an afterthought before the season, are right there.

Here's the thing, though: Neither team has done much against quality opponents this year, aside from New England's hardfought 16-10 victory in Buffalo way back in Week 3. New England is 10-2, but they were beat convincingly in their two most challenging games this year — road matchups with the Baltimore Ravens and Houston Texans — which has led to questions about whether the Brady-Belichik partnership might be winding down.

Buffalo, meanwhile, has only beat one team that currently has a winning record, and it's fair to say that the Tennessee Titans were nowhere near as good as they are now when that happened.

Both teams will be up against a major test Sunday with a chance to buck the trend. New England will host the Kansas City Chiefs and reigning MVP quarterback Patrick Mahomes, while the Bills have the luxury of playing the Baltimore Ravens, the hottest team in the league thanks to potential 2019 MVP quarterback Lamar Jackson. Per The Ringer, New England will need its statistically-impressive defense to play like it has against its non-Houston and Baltimore opponents, while Buffalo will need its improving quarterback Josh Allen to step up against Jackson.

President Trump may have gotten a good response from his audience, but his latest speech offended many others.

Trump delivered a 45-minute speech to the Israeli American Council in Hollywood, Florida, on Saturday evening. Trump spoke about his administration's decisions to pull out of the Iran nuclear deal in 2017, move the U.S. Embassy to Jerusalem, and eliminate funding for the Palestinian Authority as he urged those in attendance to vote for him while he runs for a second term in the Oval Office. Trump was reportedly regularly interrupted by the crowd's chants of "four more years" during the speech.

But the speech was not without controversy, with several observers noting that his words played into anti-Semitic tropes about wealth and loyalty, Haaretz reports. During the speech, Trump said there are Jewish people in the U.S. who don't love Israel enough, and added that if someone like Sen. Elizabeth Warren (D-Mass.) gets elected to the presidency, instead, the people in the room would "be out of business in 15 minutes."
