President Joe Biden is set to meet with allies from the eastern flank of NATO and NATO Secretary General Jens Stoltenberg Wednesday to shore up Western support for Ukraine, nearly a year since the Russian invasion.

The Supreme Court continues its turn to thorny issues Wednesday, as the court debates whether Twitter, Google and Facebook can be held liable under a 2016 law for “aiding and abetting” the Islamic State group. The justices will hear arguments in a case stemming from a 2017 terrorist attack at a nightclub in Istanbul, Turkey.

Here's what else is happening in politics:

• "Kyiv stands strong": Biden said the world has responded to a "test for the ages" amid heightened tensions between the U.S. and Russia.  Ahead of a NATO meeting, he said Moscow has made a "big mistake" by suspending its participation in a key arms treaty.

• 2024 race: In her first visit to Iowa since announcing she would run for president, former S.C. Gov. Nikki Haley made a direct pitch for her candidacy over former President Donald Trump.

• Breaking the glass ceiling: Democratic state Sen. Jennifer McClellan was elected Virginia's first Black woman in Congress.

• California Senate race: Democratic Rep. Barbara Lee entered the race for a highly competitive seat to replace retiring Sen. Dianne Feinstein.

• Biden Archives pick: Colleen Shogan will get a Senate committee hearing next week.

A new record of women will serve in Congress

A historic number of women will serve in the 118th Congress once congresswoman-elect Jennifer McClellan, D-Va., is sworn-into office.

A total of 150 women will serve in Congress, surpassing the previous record set at the swearing-in of the 118th Congress last month, according to Rutgers University’s Center for American Women and Politics.

Facing criticism for his administration’s handling of a trail derailment in Ohio, President Joe Biden called state and federal officials from Poland Tuesday and “reaffirmed my commitment to making sure they have everything they need.”

Biden tweeted details of how the government has responded. But the mayor of East Palestine, Ohio, has criticized Biden for going to Ukraine and Poland this week instead of to Ohio.

Former President Donald Trump planned to visit East Palestine Wednesday and donate water and cleaning supplies.

Pence: Social Security, Medicare should ‘be on the table’ long-term

If congressional Republicans don’t want to talk about entitlement reform amid the debt ceiling talks, former Vice President Mike Pence certainly does.

"While I respect the speaker's commitment to take Social Security and Medicare off the table for the debt ceiling negotiations, we've got to put them on the table in the long term,” Pence said Wednesday morning on CNBC.

The White House has been eager to goad GOP lawmakers – namely Sen. Rick Scott – for past comments on changes to entitlements.

Pence, a potential 2024 GOP presidential contender, showcased his CNBC appearance on his Twitter page and was blunt that “fiscal discipline” is a top priority in his travels across the country.

Wisconsin Supreme Court headed for high-stakes general election

Wisconsin voters decided on two judges to advance to a high-stakes general election for the highest state court after a four-way primary on Tuesday.

Janet Protasiewicz and Daniel Kelly won out in what was a nonpartisan-in-name-only primary between two liberal and two conservative judges.

The court currently has a 4-3 conservative majority, but conservative Justice Patience Roggensack announced her retirement. With a Democratic governor and Republican-controlled state legislature, control of the state's Supreme Court could decide the future of many policies in the battleground state. The general election is set for April 4.

Vivek Ramaswamy, Republican anti-‘woke’ activist, announces 2024 presidential bid

Vivek Ramaswamy, a Republican activist who made a name for himself criticizing “woke” culture in the corporate world, announced he will run for president in 2024 on Tuesday.

“We’ve celebrated our ‘diversity’ so much that we forgot all the ways we’re really the same as Americans, bound by ideals that united a divided, headstrong group of people 250 years ago,” Ramaswamy wrote in a tweet, adding he’s running for the nation’s top office to “revive” those ideals.

Ramaswamy emerged on the national stage after publishing his book "Woke, Inc.: Inside Corporate America’s Social Justice Scam," which criticizes political correctness and identity politics. He joins the GOP field that includes former President Donald Trump and former U.N. ambassador Nikki Haley.

House Judiciary Committee will hold hearing on fentanyl crisis

The House Judiciary Committee will hold a hearing next month on a surge of illicitly manufactured fentanyl being trafficked into the United States.

The hearing, which says in its title that “inaction is no longer an option,” is set for March 1 at 9 a.m. ET. The committee’s website has not yet added the hearing to its calendar.

In February, National Drug Control Policy Director Rahul Gupta called the surge the “worst drug crisis" the country's ever faced. More than 56,000 people died from overdoses involving synthetic opioids in 2020, including fentanyl — an increase of more than 56% in overdose death rates from 2019, according to the Centers for Disease Control and Prevention.

Biden calls Putin’s suspension of nuclear arms treaty a 'big mistake’

Russia’s suspension of a nuclear arms treaty is a “big mistake,” President Joe Biden said Wednesday.

Biden made the brief comment to reporters as he entered the presidential palace in Warsaw where he is meeting with leaders from nations on the eastern edge of the NATO alliance.

Russian President Vladimir Putin announced Tuesday he is suspending Moscow’s participation in New START, a strategic nuclear arms reduction treaty, the last remaining nuclear arms reduction deal between the U.S. and Russia. It limits each side to 1,550 long-range nuclear warheads.

Montana Democratic Sen. Jon Tester to run for reelection

Sen. Jon Tester, D-Mont., will run for reelection in 2024 – a win for Democrats, whose hopes of keeping control of the Senate in 2024 could come down to a few key races.

“It’s official. I’m running for reelection,” Tester tweeted Wednesday. “Montanans need a fighter that will hold our government accountable and demand Washington stand up for veterans and lower costs for families."

Described to the Daily Beast as the “only Democrat who can win” in Montana, Tester’s commitment to run again next year is a boon to the party’s efforts to stay in power in the upper chamber. Democrats need to defend 23 Senate seats in 2024, compared to 11 for the GOP.

Virginia elects first Black woman to Congress in special race

Democrat Jennifer McClellan will become state’s first Black woman in Congress after she coasted to victory in Virginia’s special election Tuesday.

McClellan, a state senator and corporate lawyer, defeated Republican Leon Benjamin, a pastor,. She will succeed Democrat Rep. Donald McEachin, who died last November, and represent a district anchored by Richmond that stretches south to the North Carolina border.

Once McClellan is sworn in, there will be a record 28 Black women in Congress. Her victory does not change the GOP margin in the House as Republicans still will be able to lose four GOP votes on bills and pass legislation.

Here's what Black women say they need from Democrats to win elections

More Black women are running for Congress, governor, and higher statewide offices than in the past; and overall, it has made political representation more diverse.

Yet Black women activists, strategists and experts tell USA TODAY they aren't accepted as the party’s face.

From the continued handwringing about Vice President Kamala Harris' electability to the electoral losses last year, Black women are demanding Democrats step up their political support – with increased financial backing, endorsements, candidate pipeline building and mentoring – in the coming months or risk deflating its most loyal bloc.

Supreme Court turns next to Twitter, terrorism and student loans

The Supreme Court turns Wednesday to a lawsuit accusing Twitter, Facebook and Google of aiding terrorism by hosting and recommending content created by the Islamic State group – a follow-up to the court's arguments Tuesday dealing with Section 230.

The lawsuit was filed by the relatives of Nawras Alassaf, a Jordanian citizen killed in an attack on a nightclub in Istanbul in 2017. The Islamic State group claimed responsibility for that attack, in which 39 people were killed.

Next week, the high court will hear arguments about President Joe Biden's $400 billion student loan relief program. Six conservative states and two individuals assert the Biden administration overstepped its authority with that effort.
