At least three Donald Trump events have been canceled this month alone. Trump was slated to make a speech on immigration in Denver on Thursday, which has now been postponed. The GOP nominee will, however, still attend a fundraiser in Aspen, Colorado. A rally in Las Vegas planned for Friday was also canceled, though he will still attend a fundraiser in Lake Tahoe that day. Another rally in Portland, Oregon, slated for August 31, was similarly nixed.
