Did Biden ever interrupt Trump's designated 2 minutes?

[edhopper]

There was a lot of cross talk, but wasn't that always started by Trump interrupting Biden's time?

It was not "both candidates".

1. Very briefly a few times to address Trump's lies...

... but not nearly as often as Trump.

2. It seems to me Biden did interrupt once but not during one of the 2 minute turns.

3. I think Biden "interrupted" at times, but trump started and continued it.

Biden had no choice but to jump in.

4. At least once during the designated 2 minutes, but I only remember once

it was very clear that this was a primary trump strategy, and not something that both candidates were anywhere near equally engaged in.

5. He did it repeatedly to call him a liar
