1. White House floats alternative funding options as shutdown looms

Earlier this week, all signs pointed to a government shutdown after Democrats said they were prepared to make a deal including $1.6 billion for border security -- but zero for a border wall.

President Donald Trump said if they didn't raise that number, he was happy to shut down the government.

ABC News Senior National Correspondent Terry Moran says momentum appeared to be building yesterday around a plan that would kick the can down the road -- a short-term spending bill to maintain the status quo.

2. Michael Flynn's sentencing delayed

Michael Flynn, Trump's former national security adviser, was supposed to be sentenced on Tuesday for lying to the FBI, but his hearing took a dramatic turn after the judge expressed "disgust" over Flynn's conduct.

Flynn's legal team suggested the FBI hadn't warned him that lying to federal agents is a felony, but Flynn admitted in court that he knew he was committing a crime. Judge Emmet Sullivan blasted Flynn for lying to investigators about his contact with the Russian ambassador.

"I'm not hiding my disgust, my disdain for this criminal offense," Sullivan said.

Flynn's attorney requested that the hearing be postponed. The judge agreed, and set a status update for March.

ABC News' James Gordon Meek and Katherine Faulders both were in the courtroom and noted a "dramatic shift" in Flynn during the hearing.

"He walked into court," Meek tells us, "thinking that this was going to be the start of his next chapter of his life ... and that's not what happened. It clearly was a blow, and he was stung by it, as were the people who were with him."

3. Bump stocks finally banned ... almost

The Trump administration on Tuesday moved to ban bump stocks, which effectively turn semi-automatic firearms into machine guns, after they were used in the worst mass shooting in U.S. history.

Gun owners will have until late March to destroy or forfeit the devices, which make it possible for certain guns to fire 800 rounds per minute.

At an Oct. 1, 2017, press conference, after 58 people were slaughtered at a concert in Las Vegas, Trump said he believed it would only take "two or three weeks" to ban bump stocks.

Yesterday's announcement came 443 days after that.
