Here's how Biden was able to sneak into Ukraine without anyone noticing

U.S. President Joe Biden’s motorcade slipped out of the White House around 3:30 a.m. Sunday. No big, flashy Air Force One for this trip -– the president vanished into the darkness on an Air Force C-32, a modified Boeing 757 normally used for domestic trips to smaller airports. The next time he turned up — 20 hours later — it was in downtown Kyiv, Ukraine.

The next time he turned up — 20 hours later — it was in downtown Kyiv, Ukraine.

Biden’s surprise 23-hour visit to Ukraine on Monday was the first time in modern history that a U.S. leader visited a warzone outside the aegis of the U.S. military — a feat the White House said carried some risk even though Moscow was given a heads-up.

Over the next five hours, the president made multiple stops around town — ferried about in a white SUV rather than the presidential limousine — without any announcement to the Ukrainian public that he was there. But all that activity attracted enough attention that word of his presence leaked out well before he could get back to Poland, which was the original plan. Aides at the White House were surprised the secret held as long as it did.

But Russia knew what the Ukrainian public did not. U.S. officials had given Moscow notice of Biden's trip.

The president had been itching since last year to join the parade of other Western officials who have visited Kyiv to pledge support standing shoulder to shoulder with Ukrainian President Volodymyr Zelenskyy in the capital.

Biden's planned trip to Warsaw, Poland, and the Presidents' Day holiday provided an obvious opening to tack on a stop in Kyiv. A small group of senior officials at the White House and across U.S. national security agencies set about working in secret for months to make it happen, national security adviser Jake Sullivan said Monday. Biden only gave the final sign-off Friday.
