Louisiana's Indian-American governor Bobby Jindal has trashed Barack Obama, saying the US President was the "most liberal and incompetent president since Jimmy Carter".
Speaking at a fund-raising lunch for Republican presidential candidate Mitt Romney in Baton Rouge, capital of Louisiana on Monday, Jindal attacked Obama for running "an increasingly desperate and negative campaign."
"We have a president who hadn't run anything before he was in the White House," Jindal said.
The governor later referred to Obama as the "most liberal and incompetent president since Jimmy Carter. No offense to Jimmy Carter," the Greater New Orleans reported.
Jindal said "Seems like every time you turn on the TV you hear another false, malicious attack. Despite the fact that independent fact checkers and the Washington Post and others have decried these attacks as false, they keep coming again and again. Why is that?"
"It's pretty simple. It's because this president, President Obama, he cannot run on his record, he can't run on his political philosophy so he has to attack and distort Gov Romney's record," he was quoted as saying by ABC news.
Jindal helped Romney raise $2 million amid speculation that he could be presumptive Republican presidential nominee's running mate in the November poll.
Romney made no direct mention of the Democratic attacks over his record at Bain Capital. But it was clear it was on the Republican nominee's mind as he addressed a room of supporters.
"I'm not going to apologise for being a successful businessman," he told donors. "Those that take risks sometimes succeed brilliantly, wonderfully; and that makes us a stronger economy."
Obama team had last week raised questions about Romney's connection to venture capital firm Bain Capital, accused of outsourcing jobs to China and India.
