One of President Trump's "longest standing supporters," New York Yankees president Randy Levine, published a scathing open letter Sunday night that ripped Trump for supporting "the swamp's idea of tax reform."

"The plans on the table are not middle-class tax cuts," Levine wrote at Newsmax. "They may not even be tax cuts at all. When you ran and won, you ran on draining the swamp, not giving new life to it."

On Sunday, the Congressional Budget Office found that the Republican tax plan would increase the federal deficit by approximately $1.4 trillion over the next decade, and that it would be worse for Americans earning under $75,000 than previous estimates had anticipated.

"You may think the present deal is a win because something (anything) will get passed and be chalked up as an accomplishment for your administration," Levine went on. "Nothing can be further from the truth." Levine argues that "this is a plan that helps Wall Street, hedge funds, private equity managers, real estate and oil and gas partnerships, and individuals who disguise income as profits or distributions."

As things stand Monday morning, "if the Senate can get its tax bill through this week, there's a good chance Congress could get a bill to President Donald Trump's desk by the end of the year," Politico reports. Read Levine's full letter at Newsmax. Jeva Lange

President Trump on Friday tweeted an announcement that Mick Mulvaney, Director of the Office of Management and Budget, will step in as acting White House chief of staff.

Mulvaney, who also worked as the acting director of the Consumer Financial Protection Bureau before bowing out this week, will replace current White House Chief of Staff John Kelly, who will depart at the end of the year. "Mick has done an outstanding job while in the administration," wrote Trump, "I look forward to working with him in this new capacity."

Trump additionally praised Kelly as a "great patriot" who "served our country with distinction." Trump's reported first choice to replace Kelly, Vice President Mike Pence's chief of staff Nick Ayers, turned down the job, leaving Trump to consider several administration officials and lawmakers for the post.

Gun deaths in the U.S. reached their highest point in nearly 40 years in 2017, according to a CNN analysis of a report released by the Centers for Disease Control and Prevention.

The CDC's data showed that nearly 40,000 people died by gun last year, CNN reports, which is up from 28,874 in 1999. CNN's analysis also found that more than 23,000 people died from suicide by guns, which is the highest rate in 18 years.

The report found that white men led the gender and racial demographics for gun deaths by suicide, and black men led in homicide deaths.

Former U.S. Rep. Gabrielle Giffords (D), who was nearly killed in 2011 due to a gun wound, released a statement reacting to the CDC's report.

"This data from the CDC reminds us how many lives our gun violence crisis alters every year – and why so many Americans are rising up to demand action," Giffords said. "It's unacceptable that the number of deaths from shootings keeps escalating while Washington, D.C. refuses to even debate policies we know would help save lives." Marianne Dodson

People are using the highest levels of government to come up with the world's lowest security passwords.

More than 5 million passwords were leaked this year, password manager SplashData's analysis of breached data reveals. Your standard "iloveyou" and "qwerty" made the list of the most popular passwords in the world, but so did one newcomer: "donald."

Of all the infinite combinations of letters, numbers, and symbols people could use, nearly 10 percent of internet users secured their accounts with one of the 25 worst passwords out there, per TechCrunch. After "123456" and "password," strings of numbers make up the next five "worst passwords" on SplashData's list. And making its first-ever top-25 appearance, clocking in at No. 23, is "donald."

No, SplashData's CEO assures us "this is not fake news." Hackers find "celebrity names" and other common words are often used as passwords, as are simple keyboard strings. So try passwords of at least 12 characters, and mix in some symbols and numbers, SplashData recommends. And whatever you do, don't use anything on the list below, as compiled by TechCrunch.

A DC comic series has been axed after allegations of sexual abuse emerged against its writer.

The series Border Town will cease production, and the final two issues of the comic will not be published under DC, The Hollywood Reporter wrote on Friday. The announcement comes after toy designer Cynthia Naugle published a statement saying she had been "sexually, mentally, and emotionally abused" by an unnamed person. The figure was later identified on social media as Border Town writer and co-creator Eric M. Esquivel, per the Reporter.

Two artists for the comic have since released statements on Twitter, with color artist Tamra Bonvillain calling Esquivel's actions "disgusting and inexcusable." Esquivel has not yet publicly commented on the allegations.

Border Town opened this year's relaunch of the DV Vertigo line, which publishes more mature content about hot button topics. The comic sold out and was met with critical acclaim, per the Reporter. Marianne Dodson

Wisconsin Gov. Scott Walker (R) signed legislation Friday stripping some powers from his Democratic replacement, and in the process, revealed his misunderstanding of a very elementary math concept.

Ever since Wisconsin's GOP lost the executive branch but retained the legislative one, lawmakers and the outgoing Walker have embarked on a lame-duck quest to limit the incoming administration's powers. Legislation passed by the state's legislature and signed Friday by Walker will stop governor-elect Tony Evers (D) from controlling a state economic commission and reduces time for early voting, among other things. It's very "inside baseball," as the state Senate's majority leader said, so Walker tried to explain it in a Venn Diagram.

Graduates of middle school math would notice all the "authorities" listed on both sides of the graph should go in the middle, and all the executive powers Walker just signed away should be listed only in his. But to be fair, "not understanding the most basic of graphs" is something both Democrats and Republicans could put between their two circles in a Venn diagram. Kathryn Krawczyk

George Papadopoulos doesn't see why being sent to jail for lying to the FBI should get in the way of his plans to run for Congress.

The former foreign policy adviser to President Trump's campaign told The Telegraph on Friday that he will run for Congress in 2020, saying he always intended to use his connection with Trump "as a platform to run for office myself." Papadopoulos said his "end game remains the same," even though "things just took a different direction," by which he means he was convicted for lying to federal investigators and is on supervised release for the next year.

He didn't specify where he's going to run, but it sounds like he's not picky, saying, "I just have to find a little Republican enclave somewhere in this part of the world, in this part of the country I should say, and run there." In fact, he claims he already has "some support."

On Twitter, Papadopoulos doubled down, tweeting a simple message to those who have suggested the best time to launch a congressional bid isn't necessarily seven days after getting out of jail: "It is true," he wrote. "I will be running for Congress in 2020, and I will win. Stay tuned." Brendan Morrow
