The former first lady is in the Mile High City.

Michelle Obama is in Denver to speak at an event sponsored by the Women’s Foundation of Colorado to celebrate its 30th anniversary Tuesday night at the Pepsi Center. More than 8,000 people had bought tickets as of Tuesday morning.

“She has inspired many girls with her story and her fierce commitment to creating access to education for girls,” WFCO President and CEO Lauren Casteel said in a statement. “We are thrilled that she is joining us.”

Casteel will be moderating the conversation with Obama. Eight local teenagers, members of the 2017 Girls’ Leadership Council, will introduce the former first lady.

Obama’s popularity led the organization to open up more seats to the event starting at 5:30 p.m., and tickets were still available as of midday Tuesday.

Michelle and Barack Obama have both been on speaking tours following a post-presidency vacation. Michelle Obama has largely steered clear of politics, focusing instead on topics that she advocated for as first lady, including education for women and health and nutrition for schoolchildren.

She spoke at the American Institute of Architecture’s annual conference in April, The Partnership for a Healthier America summit in May and the Pennsylvania Conference for Women in October.
