Ukrainian President Volodymyr Zelensky is preparing to meet with Joe Biden on a visit to Washington today which would be his first trip outside the country since Russia's invasion.
Congressional sources have confirmed that Zelensky is to travel to the United States on a highly sensitive trip and it could be called off at any moment due to security concerns.
It comes as the US has announced it will send $1.8 billion in military aid to Ukraine in a massive package that will include for the first time a Patriot missile battery and precision guided bombs for fighter jets.
