"We're going to send some more weapons – we have to. They have to be able to defend themselves," Trump said of Ukraine July 7.

Medvedev is deputy to Russian President Vladimir Putin on the Security Council of Russia, which advises Putin on national security and strategic matters, and is himself a former president and prime minister of the country.

Donald Trump has promised to send more weapons to Ukraine after Russia turned down White House calls for a ceasefire and peace talks. The US president said Ukraine is being ‘hit very hard now’ by the Kremlin’s missile and drone strikes, some of which hit the capital Kyiv just hours after he got off the phone with Vladimir Putin.
