The White House is reportedly trying to sway European leaders to accept an agreement that would include Russia taking the entire Donbas region in eastern Ukraine and keeping Crimea. In exchange, it would give up the Kherson and Zaporizhzhia regions, areas which Russia is partially occupying, CBS reported.

"The presidents will undoubtedly focus on discussing ways to reach a sustainable settlement to the Ukraine crisis," a Kremlin aide said on Saturday.
