Biden says Zelenskyy's statements on Poland missile incident are 'not evidence'

President Joe Biden was asked by reporters Thursday what his reaction was to Ukrainian President Volodymyr Zelenskyy denying that the missile that landed in Poland was Ukrainian.

"That's not the evidence," Biden responded.

On Wednesday, the White House told reporters it had "seen nothing" to contradict the assessment that the explosion in Poland was likely caused by a Ukrainian defense missile.

"We will continue to assess and share any new information transparently as it becomes available. We will also continue to stay in close touch with the Ukrainians regarding any information they have to fill out the picture," National Security Council spokesperson Adrienne Watson said in a statement.
