US President Joe Biden to visit war-torn Ukraine soon? Know what he said

US President Joe Biden said on Tuesday that he does not know if he will travel to the capital city of Kyiv after Ukraine's wartime leader called on him to visit.

"The answer is, I don't know," Biden said when asked by reporters at an event in New Hampshire whether he would visit the Ukrainian capital.

Ukraine President Volodymyr Zelenskyy said in a CNN interview aired on Sunday that he wanted Biden to visit and expected that he would.

The White House has said Biden is not likely to go but that they are considering whether to send a high-ranking US official to meet and show solidarity with Zelenskyy as he faces an intensifying Russian attack in the east of the country.

Sources familiar with the situation have floated Defense Secretary Lloyd Austin or Secretary of State Antony Blinken as possible US officials to make the trip but that Biden and Vice President Kamala Harris were unlikely due to security concerns.

"If and when that happens, we'll want to make sure it is done in a very secure way," Biden national security adviser Jake Sullivan said in an interview last week at the Economic Club of Washington DC.

Other Western leaders, including British Prime Minister Boris Johnson and European Commission President Ursula von der Leyen, have made trips to Ukraine following Russia's invasion in February.
