 A lot of eyes are on the president today as he holds his first solo press conference since that shaky presidential debate late last month. Democrats have been in disarray ever since. The president and his team have been trying to quiet worries, but the questions about Biden's age, health and acuity aren't going away. The president has another chance to prove he's still up for the job as he meets with Ukraine's President Volodymyr Zelensky and tries to show his leadership in coordinating allies and strengthening the NATO alliance.
