 AP News. I'm Ed Donoghue. Texas Congressman Lloyd Doggett is the first Democrat to publicly call on President Biden to step aside. In a statement, Doggett said in last week's debate, the president failed to effectively defend his many accomplishments and should make the painful and difficult decision to withdraw. Meantime, in Washington, the president is proposing a new rule to address excessive heat in the workplace. This includes things like developing response plans to heat illness.
