Does Anthony Weiner ever learn?

The former Congressman tweeted criticism on Thursday of Gov. Andrew Cuomo's shutdown of the subways during last month's forecasted blizzard, but Cuomo's spokesperson had a quick comeback for him.

"Sunday's gonna be cold," Weiner tweeted. "Governor Cuomo will soon be closing the subway."

Rich Azzopardi responded: "Yes, it's going to be cold. A good reason to keep your pants on."

It didn't look like Weiner was ready to let the matter drop. He then tweeted "I have to be careful with responding. I don't want to be accused of witness tampering." Azzopardi didn't respond to this tweet.

How did politicians ever insult each other before Twitter?
