 Story from the Texas Tribune. Congressman Lloyd Doggett, Democrat, called on President Joe Biden to step down as his party's nominee for the White House on Tuesday, citing the president's poor performance at a debate against former President Donald Trump last week. Doggett said in the statement, President Biden has continued to run substantially behind Democratic senators in key states and in most polls has trailed Donald Trump. I hope that the debate would provide some momentum to change that it did not.
