(AP) -- New York City Mayor Bill de Blasio is rejecting Uber's call to have a live debate about their differences.

The ride-hailing service invited de Blasio on Monday to participate in a live-streamed conversation about the company's future in New York. The de Blasio administration is trying to slow down Uber's rapid expansion.

De Blasio declined the invitation, saying he doesn't debate private corporations. He added that, in his words, "Uber is a multibillion-dollar corporation, and they're acting like one."

His administration supports a proposal to cap Uber's growth for a year while its impact is studied. The City Council is expected to weigh the proposal this week.

San Francisco-based Uber has rejected all attempts to slow its growth. It says de Blasio is trying to stifle free enterprise and innovation.
