DETROIT (AP) — U.S. Rep. Thaddeus McCotter will make a "major announcement" Saturday about whether he will run for president in next year's election, a person familiar with the plans said Thursday. McCotter's office said Thursday that the 45-year-old will be the keynote speaker Saturday at a festival in Whitmore Lake. "He's going to make a major announcement at that event," the person, who is in contact with the Livonia congressman, told The Associated Press.
