It is worth mentioning that Lieutenant Colonel Alexander Vindman earlier stated that he had received a proposal to fill the post of the Secretary of Defense of Ukraine from ex-Secretary of National Security and Defence Council Oleksandr Danylyuk.
As we reported earlier, U.S. President Donald Trump tweeted he will “strongly consider” House Speaker Nancy Pelosi’s suggestion over the weekend that he testifies in the House of Representatives' impeachment inquiry, CNN informed.
