A major prisoner exchange between Russia and Ukraine is now under way, according to a Ukrainian source familiar with the matter.

President Trump announced on Friday that Ukraine and Russia were conducting a major prisoner exchange after the two warring countries agreed a week ago to swap 1,000 prisoners each as part of cease-fire negotiations.

“Before I even arrive at the Oval Office, shortly after we all together win the presidency, we will have the horrible war between Russia and Ukraine settled. It will be settled. The war is going to be settled. I’ll get them both. I know Zelensky, I know Putin. It’ll be done within 24 hours, you watch.”
