WASHINGTON The Latest on the Republican National Convention (all times local):5:15 p.m.A speaker who had been expected to deliver remarks on the third night of the Republican National Convention has been unexpectedly removed from the program hours before airtime. Also unclear is the status of a speech by former professional football player Jack Brewer. Brewer was charged with insider trading by the U.S. Securities and Exchange Commission earlier this month. The campaign would not say definitively whether he will speak. Organizers on Tuesday pulled another featured speaker, Angel Mom Mary Ann Mendoza, after she directed her Twitter followers to a series of anti-Semitic, conspiratorial messages hours before her prerecorded segment was set to air.
