Mitt Romney took out the knives after President Obama needlingly suggested that his GOP rival was born with a silver spoon in his mouth.
The Republican presidential candidate, whose wealth is estimated upwards of $250 million, accused the president of "attacking people" instead of the nation's problems, and said he had nothing to be sorry for.
“I'm not going to apologize for my dad and his success in his life," Romney said Thursday on "Fox & Friends."
"He was born poor and he worked his way to become very successful despite the fact that he didn't have a college degree, and one of the things he wanted to do was provide for me and for my brother and sisters," the former Massachusetts governor added.
The White House hopeful's father, George Romney, served as the governor of Michigan and chairman of American Motors Corp.
Obama's subtle dig came Wednesday during a speech to Ohio's Lorain County Community College, during which he reiterated the need for government assistance to the less fortunate.
"Somebody gave me an education. I wasn't born with a silver spoon in my mouth," said the President. "Michelle wasn't. But somebody gave us a chance, just like these folks up here are looking for a chance."
Romney said Obama was merely "looking for a scapegoat, particularly those that have been successful like my dad."
