Trump's tweet today about Michael Flynn was expected — he can't help but fire off on Twitter when he's upset about something. But he likely wasn't expecting the tweet to set off alarms about whether he obstructed justice.

Between the lines: Trump tweeted "I had to fire General Flynn because he lied to the Vice President and the FBI." This suggests Trump knew that Flynn lied to the FBI when he met with former FBI Director James Comey (after Flynn resigned) and specifically asked him to let the investigation of Flynn go.

Why it matters: Until now, it was understood that the White House only recently learned about Flynn lying to the FBI, which he admitted yesterday in court. But Trump and White House administration officials will likely have to answer for this tweet because it introduces a new piece to the Russia puzzle that Bob Mueller could specifically use to get more information about how much Trump knew.

Be smart: Trump confidants are worried about an obstruction of justice case being built against Trump, according to Mike Allen's reporting this morning. But a tweet isn't going to get Trump in legal trouble, and any legal action against him or anyone in his inner circle would take weeks of probing by Mueller and his team.

In her first week on the job, Amy Coney Barrett may be deciding which votes to count in the presidential election. By her third week, she’ll be deciding the fate of the Affordable Care Act.

Where it stands: The Senate votes on Barrett’s nomination tomorrow. If she’s confirmed, Chief Justice John Roberts is expected to swear her in at the Supreme Court within hours, an administration official tells Axios.

Texas Democrats beg Biden to spend now

The Biden campaign is rebuffing persistent pleas from Texas Democrats to spend at least $10 million in the Lone Star state, several people familiar with the talks tell Axios.

Why it matters: If Texas — which has 38 electoral votes and is steadily getting more blue, but hasn't backed a Democrat for president since 1976 — flipped to the Biden column, it would be game over. But the RealClearPolitics polling average stubbornly hovers at +2.6 for Trump — and Team Biden appears more focused on closer targets.

Election night in Trumpworld

A luxe election-night watch party at the Trump International Hotel on Pennsylvania Avenue is being planned for President Trump's donors, friends and advisers — but Trump's hand in it is minimal because he's "very superstitious" — people familiar with the plans tell Axios.

The big picture: This "mecca for all things MAGA," as one adviser described it, is one of three hubs where they say Trumpworld will watch returns. The others are the war room at campaign HQ in Rosslyn, Virginia, and the White House residence, where Trump and the first lady will gather close family and advisers before heading to the hotel later that night, the sources said.
