Debate commission adopts new rules to mute mics

President Donald Trump and Democrat Joe Biden will have their microphones cut off in Thursday's debate while their rival delivers their opening two-minute answer to each of the debate topics.

The 90-minute debate is divided into six 15-minute segments, with each candidate granted two minutes to deliver uninterrupted remarks before proceeding to an open debate. The open discussion portion of the debate will not feature a mute button, but interruptions by either candidate will count toward their time in the second and final debate on Thursday.

The nonpartisan Commission on Presidential Debates announced the rule changes on Monday, three weeks after a chaotic opening faceoff between the two presidential contenders that featured frequent interruptions -- most by Trump.

The commission has faced pressure from the Trump campaign to avoid changing the rules, while Biden's team was hoping for a more ordered debate.

In a statement, the commission said it had determined that it is appropriate to adopt measures intended to promote adherence to agreed upon rules and inappropriate to make changes to those rules .
