NBC News was forced to cut to a commercial break during the first 2020 Democrat presidential debate after due to technical difficulties.

As debate moderators Rachel Maddow and Chuck Todd took over Wednesday for the next round of the debate, the 10 candidates on stage were unable to hear the question Todd was trying to ask about the federal government’s role in getting guns off the street.

Following back-and-forth confusion, Todd announced the debate would head to a commercial break.

It wasn’t immediately clear what happened.

President Donald Trump tweeted that debate hosts NBC and MSNBC “should be ashamed of themselves for having such a horrible technical breakdown in the middle of the debate.”
