Warren congratulates Biden on SC primary win

Democratic presidential candidate Massachusetts Senator Elizabeth Warren is congratulating former Vice President Joe Biden for his decisive win in South Carolina.

Warren says her presidential campaign is moving forward to Super Tuesday after falling short in another primary.

Speaking at a rally Saturday night in Houston, Warren says the first four contests hadn't gone exactly as she hoped.

But, Warren says her campaign "is built for the long haul."

She also says full results from Super Tuesday may take days to emerge but will be critical to deciding the Democratic presidential nominee.

Warren had her best finish of the primary season in Iowa's first-in-the-nation caucuses, finishing third. She finished fourth in both New Hampshire and Nevada and could finish worse than that in South Carolina.
