Here's where you can sign up and listen in.
This is U.S. Sen. Cory Gardner's first semi-public meeting since Republicans released their replacement plan for the Affordable Care Act. Gardner hasn't weighed in yet on the specifics of the bill, though a few hours before the bill was filed, he and three other Republican senators signed a letter in opposition to the Medicaid policies in an earlier draft version of the legislation.
The final legislation contains a similar approach to reducing Medicaid spending -- switching from an entitlement program to a per-capita cap on spending per enrollee -- but also allows the Medicaid expansion to continue through the end of 2019 before freezing new enrollment.
As U.S. Rep. Mike Coffman noted on a radio show Tuesday, this approach constitutes a major entitlement reform to the Medicaid program.
The telephone town hall isn't limited to health care questions, but the issue was already very much on people's minds.
To get a chance to ask a question, you need to sign up at least an hour before the town hall. It's scheduled to start at 7:10 p.m. local time.
At Gardner's most recent telephone town hall last week, about a dozen people got to speak out of an estimated 10,000 people listening. We talked to some of those folks about their experience.
Two other Republican representatives -- Doug Lamborn and Scott Tipton -- are also holding telephone town halls tonight.
Coffman has said he'll hold telephone town halls specifically on health care later this month, but the times and dates haven't been announced yet.
