Elon Musk praised a Putin ally for trolling the UK's prime minister over her resignation.
On Thursday, Dmitry Medvedev trolled UK Prime Minister Liz Truss for resigning after only 44 days in office, and alluded to a running joke in UK tabloid The Daily Star about whether she'd last longer than a lettuce.
Musk was criticised for the jokey interaction with Medvedev, who has previously served as prime minister and president of Russia, and now leads its security council.
Musk, the world's richest man, has recently made a series of outspoken pronouncements on the Ukraine war and tensions between Taiwan and China.
Fiona Hill, a former White House Russia expert, said Putin was likely manipulating Musk.
