President Joe Biden in his State of the Union address announced the U.S. will ban Russian flights from its airspace, joining Canada and the European Union, which issued bans on Russian planes in their respective airspaces over the weekend.

"Tonight I am announcing that we will join our allies in closing off American air space to all Russian flights -- further isolating Russia -- and adding an additional squeeze on their economy," Biden said.

The ban will apply to "operations of all aircraft owned, certified, operated, registered, chartered, leased, or controlled by, for, or for the benefit of, a person who is a citizen of Russia," according to the Federal Aviation Administration. "This includes passenger and cargo flights, and scheduled as well as charter flights, effectively closing U.S. air space to all Russian commercial air carriers and other Russian civil aircraft."

The ban will be "fully effective" by the end of the day Wednesday, the FAA said.

While all eyes in Washington are on President Joe Biden's State of the Union address, some lawmakers have been working the phones to rally support at the United Nations for a resolution before the General Assembly to condemn Russia's invasion of Ukraine and call for a peaceful resolution.

Working with the United States Mission to the United Nations, Democrats on the House Foreign Affairs Committee have identified more than a dozen countries to target and called for ambassadors and key diplomats to leverage relationships to build more support for the nonbinding resolution.

"This has been a way for Congress to really play an important role working with the executive branch in getting this done and showing the world that Russia's actions are illegal and should be condemned," Rep. Joaquin Castro, D-Texas, a senior member of the committee that is leading the effort, told ABC News.

The vote "is an opportunity for countries to take a stand, and it's especially a chance for the United States to demonstrate leadership among the nations of the world," he said.

"President Biden and his administration, and now Congress, I believe, have demonstrated our ability to marshal our allies to condemn something the world has worked for decades to root out -- which is a sovereign nation invading another."

Republicans have also been working to build support for the measure in the General Assembly, Castro said.

Ukrainian Foreign Minister Dmytro Kuleba addressed the accounts of racism at the border by people of color attempting to flee, tweeting Tuesday, "Ukraine’s government spares no effort to solve the problem."

Germany Foreign Minister Annalena Baerbock also addressed the reports of racism and discrimination during a powerful speech at the U.N. Assembly on Tuesday.

"Every refugee must receive protection, no matter what their nationality, no matter what their religion, no matter of the color of their skin," Baerbock said.

Despite debate within the U.S. administration on whether Russia is suffering military setbacks in Ukraine, a senior U.S. official reiterated to ABC News that the invasion will be devastating for Ukraine.

"Putin is going to put Ukraine in a vice grip," the official said, adding that Putin has ratcheted up his determination to carry on.

The dominant analysis within the administration involves Putin acting out with incredible ferocity and intent, believing this is his destiny, the official said.

The massive Russian convoy heading toward Ukraine is just as mighty as it looks from satellite imagery, the official added.

Taking out just half a dozen of those tanks would seriously slow down the convoy, because the roads are surrounded by mud in many places, so it would be difficult for the tanks to maneuver around the crippled vehicles, the official said.

President Joe Biden is under pressure to act, but the U.S. military is wary about any proposals that would bring American troops into open conflict with Russia. The U.S. military is also adamant that about avoiding anything that would trigger conflict, the official said.

The United Nations High Commissioner for Human Rights has "received credible reports of several cases of Russian forces using cluster munitions, including in populated areas," spokesperson Elizabeth Throssell said Friday.

"Due to their wide-area effects, the use of cluster munitions in populated areas is incompatible with international humanitarian law principles," Throssell said.

Throssell added, "We remind Russian authorities that directing attacks against civilians and civilian objects as well as so-called bombardment in towns and villages and other forms of indiscriminate attacks are prohibited under international law and may amount to war crimes."

To date, there have been 26 attacks on health care facilities in Ukraine, killing at least 12 people and injuring 34 people, according to Jašarević. Two of those killed and eight of the injured were healthcare workers.

That number is "shocking," said Throssell.

Throssell and WHO spokesperson Tarik Jašarević declined to pin the blame for all of them on Russia.

This number of attacks includes Wednesday's strike on a children's hospital and maternity ward in Mariupol. On Thursday, Russian officials claimed that the attack was staged, but they first confirmed they bombed it and claimed the hospital was being used by Ukrainian "radicals."

Throssell told reporters that is not true; "It was a functioning hospital," she said.
