Donald Trump teases his pick for vice president at his campaign speech in FloridaFormer President Donald Trump teased his vice president at Tuesday night's Florida rally as he nears the deadline to announce his running mate. “They probably think I’m going to be announcing that Marco is going to be vice president,” Trump said of Florida Sen. Marco Rubio, who was sitting in the front row and spoke earlier in the night. When discussing about his commitment to make tips tax-free, Trump said that Rubio "may or may not be there to vote for it." Trump has often said that he intends to reveal his nominee shortly before or during the Republican National Convention, which begins next Monday in Milwaukee, Wisconsin. But Trump does not seem in a rush because most of the public attention is still on Biden's chance to run for another term as some Democrats began to call for Biden to step down following his disastrous performance at the presidential debate last week.
