The other side: Biden did receive public support from several senators today, including from Sen. Gary Peters (D-Mich.), the chair of the Democratic Senatorial Campaign Committee. 

• "I believe President Biden can win," Peters said, according to the Detroit News. "And I believe that we'll be able to hold the Senate majority."
• When Sen. Bob Casey (D-Pa.) was asked by reporters Wednesday if he agreed with [Colorado Sen. Michael] Bennet that Biden was in danger of losing, Casey responded: "No."
• "The president can win and I think he will win," Sen. Bernie Sanders (I-Vt.) said.
