Trump tells Biden not to 'fall asleep' during meeting with Putin

Former US President Donald Trump wished President Joe Biden ''good luck'' Thursday in his upcoming meeting with Russian President Vladimir Putin and also jokingly gave him some last-minute advice.

''Good luck to Biden in dealing with President Putin—don’t fall asleep during the meeting, and please give him my warmest regard!'' Trump said in a statement.

During his presidential campaign against Biden, the country 45th president nicknamed his successor ''Sleepy Joe.''

Trump said he had a ''great and very productive meeting'' with Putin when he was president and the US won the respect of Putin and Russia.
