UPDATE: The Nevada event is confirmed. The Colorado one was called off due to the mass shooting there last week.

ABC News: Sen. Marco Rubio, R-Fla., is set to make some high profile surrogate appearances on behalf of Mitt Romney next week in Colorado and Nevada, campaigning solo for the presumptive GOP nominee for the first time, ABC News has learned.

A source with knowledge of the events told ABC News Rubio will campaign for Romney at a rally at Rubio’s old elementary school in Las Vegas, Nevada, Saturday followed by a rally in Denver, Colorado, later that day. Rubio also will participate in finance events for Romney while in the area.
