Watch Live: Biden to deliver remarks on Ukraine as U.S. prepares to send tanks

Washington — President Biden is set to deliver remarks on the United States' "continued support for Ukraine" on Wednesday as the U.S. prepares to send tanks to the country to provide much-needed firepower for Ukrainian troops fighting off Russian invaders.

As CBS News reported Tuesday, the U.S. is now poised to send dozens of its top-of-the-line battle tank, the M-1 Abrams, to Ukraine after insisting for weeks that the systems were too complex to operate and maintain. Ukraine has been asking for the Abrams tanks for months amid fierce fighting in the country's disputed east.

The U.S. officials cautioned that it will take some time to deliver the tanks and train Ukrainian soldiers to operate and maintain them effectively. But once operational, the tanks will give Ukraine major new capabilities to launch offensives against dug-in Russian troops.
