President Trump escalated his continuing war of words with former White House staffer Omarosa Manigault Newman on Tuesday, calling her a "dog" in a morning tweet.

"When you give a crazed, crying lowlife a break, and give her a job at the White House, I guess it just didn’t work out. Good work by General Kelly for quickly firing that dog!"

The big picture: As one former senior White House official told Axios' Jonathan Swan over the weekend: "She may be the purest of all the Trump characters. ... She may be the most Trumpian. She knows media, she knows about physical presence, like Trump does...that's why I think he's rattled."

Republicans in Pennsylvania on Monday asked the U.S. Supreme Court to halt a major state court ruling that extended the deadlines for mail-in ballots to several days after the election, The Morning Call reports.

Why it matters: It's the first election-related test for the Supreme Court since the death of Justice Ruth Bader Ginsburg, and could decide the fate of thousands of ballots in a crucial swing state that President Trump won in 2016. What the court decides could signal how it would deal with similar election-related litigation in other states.

Democrats on Trump tax story: "This is a national security question"

House Speaker Nancy Pelosi said Monday that the New York Times report that President Trump has hundreds of millions of dollars in debt coming due within the next four years is a "national security question," and that the public has a "right to know" the details of his financial obligations.

The big picture: Democrats have already leapt on the Times' bombshell, which Trump has dismissed as "total fake news," to attack the president for allegedly paying less in federal income taxes than the average middle-class household.
