No Republicans supported Reid’s use of the ‘nuclear option’.
The Republicans couldn't do anything about it, because Reid used a parliamentary procedure to unilaterally change the rule.
The next chance for Republicans to express displeasure at this was the vote on the bill, and that's where the 12 Republicans broke with the caucus and voted for the bill anyway.
The comment from Levin was that Obama was going to veto the bill anyway, so voting for it instead of showing solidarity was pointless.

Apparently there were two votes one of which was the "nuclear" option. DeMint said they needed to remain united for both votes. I'm not sure I understand but you can listen to Mark and DeMint talking about it here:
