Former U.S. Vice President Joe Biden raised $8.9 million in January, ending the month with $7.1 million in cash, an improvement after he struggled at times last year to raise money.
Biden out-raised rival former South Bend, Indiana Mayor Pete Buttigieg, who raised $6 million during the same time, but was vastly out-raised by U.S. Senator Bernie Sanders, who raised $25 million in January.
