The Director of the U.S. Central Intelligence Agency, CIA, John Ratcliffe, on Wednesday said the United States has cut off intelligence-sharing with Kyiv in a move that could seriously hamper the Ukrainian military’s ability to target Russian forces.

The United States has temporarily cut off intelligence sharing with Ukraine, officials said on Wednesday, the latest blow to the relationship between the Trump administration and Kyiv. CIA Director John Ratcliffe confirmed the decision in an interview with Fox News on Wednesday morning.

Officials say the halt in assistance is a warning to the Ukrainians of the consequences of not cooperating with the president.
