Ukrainian Prosecutor General Yuriy Lutsenko has said that he is willing to meet with U.S. law enforcement officials to share materials of the Burisma probe and to ask them to check the activities of some U.S. citizens in the case.

"I am ready and willing to meet with the leadership of the U.S. law enforcement agencies to provide them with all necessary materials so that they can check the legality of actions of all U.S. citizens implicated in the Burisma case," Lutsenko said in an interview with Ukrainian television channels on Tuesday.

That is beyond his scope of competence, but he is open to international cooperation in probing the case, Lutsenko said. "I believe it would be nice if all those citizens answered those questions and an end was put to the scandal that is being used for political purposes," he said.

"The message for Ukraine is quite easy to understand: from the perspective of Ukrainian legislation, we are now seeing no violation of Ukrainian laws by American citizens in the Burisma case," Lutsenko added.

Burisma Group is a company specialized in energy exploration and development operations. It has been working in the Ukrainian oil and gas market since 2002.
