Trump wants Biden to take 'drug test' before debate

WASHINGTON, Aug 27 (AFP): US president Donald Trump said Wednesday he will call for a "drug test" for himself and Joe Biden before the first presidential debate, but did not offer any evidence for his suspicions about his Democratic opponent.

Trump said in an interview with the Washington Examiner that he was intrigued by Biden's improved performance during the Democratic primary.

"We're going to call for a drug test," Trump said, expressing surprise at the former vice president's bearing during the last debate against Vermont senator Bernie Sanders in March.

The president has no concrete evidence to support his claims, but, he said, "all I can tell you is that I'm pretty good at this stuff.

"I watched him in the debates with all of the different people," Trump said, referring to the other Democratic presidential hopefuls.
