New York Sen. Kirsten Gillibrand called on President Trump to "immediately resign" yesterday, prompting a disparaging Twitter response from POTUS this morning:

Lightweight Senator Kirsten Gillibrand, a total flunky for Chuck Schumer and someone who would come to my office “begging” for campaign contributions not so long ago (and would do anything for them), is now in the ring fighting against Trump. Very disloyal to Bill & Crooked-USED!— Donald J. Trump (@realDonaldTrump) December 12, 2017

Gillibrand fired back with a tweet of her own, stating that Trump had brought "unfitness and shame" to his office:

You cannot silence me or the millions of women who have gotten off the sidelines to speak out about the unfitness and shame you have brought to the Oval Office. https://t.co/UbQZqubXZv— Kirsten Gillibrand (@SenGillibrand) December 12, 2017

Amy Coney Barrett's immediate impact

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.
