U.S. Democratic Rep. Jamie Raskin has sent a letter to U.S. President Joe Biden asking him to consult with his party colleagues on whether to continue his bid for re-election. "There's no shame in bowing to the enthusiastic appreciation of the crowd when your arms are already worn out," Raskin said in the four-page letter, comparing Biden to a tired baseball pitcher. Raskin confirmed the authenticity of the letter on Thursday.
