Former Vice President Al Gore will make two stops in Colorado Monday as Democrats try to close the deal with voters.

Gore will emphasize the importance of action on climate change and contrast Hillary Clinton’s plans to reduce emissions with Donald Trump’s statements that climate change is a hoax, according to a press release from the Clinton campaign.

Gore will appear at eTown Hall, 1535 Spruce St., in Boulder at 4 p.m. Doors open at 3 p.m. You can RSVP here.

Gore will be in Lakewood at the Lakewood Cultural Center Theater, 470 S. Allison Parkway, at 7 p.m. Doors open at 6 p.m. You can RSVP here.

Democrats have sent a string of heavy hitters to Colorado in the last week, including Chelsea Clinton, Bill Clinton, Bernie Sanders and Lena Dunham.

Donald Trump made two personal appearances in Colorado on the last two Saturdays before the election, while his running mate Mike Pence, his son Donald Trump Jr., Newt Gingrich and Ben Carson made stops as well.
