The chairman of the Democratic National Committee, Tom Perez, said on Tuesday that the party organization would reschedule next week’s presidential primary debate in Iowa if the televised event conflicts with President Donald Trump’s impeachment trial in the Senate.

“Democrats and our senators can walk and chew gum,” Perez told MSNBC. “Obviously, if there’s a trial on the 14th, then we’ll move the debate. If there’s not, then we’re going to have the debate. At the moment, all systems are go, and so we’re going to move forward.”

Of the five White House candidates to have qualified thus far for the debate next Tuesday at Drake University in Des Moines, co-hosted by CNN and The Des Moines Register, three are senators: Amy Klobuchar of Minnesota, Bernie Sanders of Vermont and Elizabeth Warren of Massachusetts.

Also slated to participate are former Vice President Joe Biden and former Mayor Pete Buttigieg of South Bend, Ind.
