MSNBC host Ed Schultz escalated a feud between himself and Sen. Marco Rubio (R-FL) Thursday with an epic rant against the senator's stance on entitlements.

In a speech at the Reagan Library last week, Rubio had claimed that Social Security, Medicare and Medicaid had actually "weakened" Americans.

Schultz responded by declaring the speech "flat-out psycho talk."

By Wednesday, Rubio's PAC, Reclaim America, was fundraising off of Schultz's criticism.

Schultz tore into Rubio again Thursday, calling his assertion that entitlements "weaken" America "A-1, flat out stupid."

"This man is suggesting that there is a generation of Americans that care less about their parents because of Social Security, Medicare and Medicaid," Schultz explained. "This may be one of the most offensive things I have ever heard a United States senator say about the people of this country."

Then Schultz went on to tell a story about how his own parents depended on the social safety net.

"My mother was an English teacher, my father was an aeronautical engineer who worked for the government. They paid for Social Security, they collected Social Security. My dad had his heart reworked and Medicare paid for it. He paid into that system for years... and I want to tell you, Mr. Rubio, that my parents went through the depression, and my parents did the World War II thing. My parents lived in the unselfish generation. And for you to say they were lesser Americans because they were involved in Social Security, Medicare and Medicaid, you owe my family at least an apology or at least be brave enough to give an explanation on this program in front of the camera as to what the hell you're really talking about."
