Rep. Devin Nunes (R-CA) should find another line of work after filing a widely-ridiculed lawsuit against parody Twitter accounts, former Sen. Barbara Boxer (D-CA) explained on MSNBC's "Hardball" with Chris Matthews on Tuesday.

"Congressman Devin Nunes (R-CA) -- as we know, a close Trump ally, very close -- is suing Twitter and three of its users for $250 million dollars, a quarter of a billion dollars, accusing them of defamation and negligence," Matthews noted. "He also accuses Twitter of being biased against conservatives."

"What do you make of this guy?" Matthews asked the former senator

"I think Harry Truman said, 'if you don't like the heat, stay out of the kitchen.' This is a guy who's been playing ball with Trump in the back room for at least two years and now he's getting hurt feelings," Matthews continued. "Your thoughts?

"I'm so sorry, Devin, you picked the wrong career," Boxer replied.

"The fact of the matter is when you go into politics, you certainly have some protections, but believe me, the courts have ruled because you have a bully pulpit and a platform, you've got to take it on the chin," she explained.

"He needs to grow up and do something else because this is absurd," Boxer counseled.

"You got to stand up and take it on the chin when you're an elected official. Donald Trump doesn't know how to do it," she noted. "He can give them, but he doesn't want to get them."

"And this is why the whole thing is outrageous and Devin Nunes needs to choose a different career," Boxer concluded.

"I think he needs his diapers changed," Matthews chimed-in.
