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.

Ukraine Defense Minister Oleksy Reznikov on Friday accused Russia of preparing to carry out airstrikes against Belarusian villages close to the border with Ukraine in order to create a pretext for Belarus entering the war more directly.

Until now, Belarus has largely only acted as a base for Russia’s invasion forces and for missile and air strikes to be launched from its territory.

Ukraine claims it has information that Russia is planning to launch a series of false flag airstrikes against Belarusian villages to try to change that and create a push for war within Belarus, Reznikov said in a post online.

"I appeal to the Belarusian people. Friends. According to information in which we are completely sure and which we have confirmed, at the present moment the command of the Russian occupation troops is preparing a series of bloody provocations," he said.

Reznikov added, "According to their criminal conspiracy, Russian aviation is preparing to launch a strike on a range of population centers on the territory of Belarus, located close to the Ukrainian-Belarusian border."

He named the village of Kopani in the Brest region.

He denied Ukraine would ever launch strikes and said, "the goal of the provocation is to push the acting leadership of Belarus towards war against Ukraine. Moscow is trying to bind you with blood."
