Romney will quite probably follow suit.
If two more do likewise (doubtful), it's dueling witnesses for another couple of weeks.

If one more does (possible), then things get rather interesting. Tied vote on impeachment would be a precedent setting situation.

Who breaks the tie?
Pence or Justice Roberts.

The airwaves will be chockers with constitutional lawyers.
