Vermont Sen. Bernie Sanders says he will decide "soon" whether he will challenge Hillary Clinton in the Democratic primary.
Sanders tells Fox Sunday News that he is trying to determine if he can raise enough money to run a viable campaign.
Sanders — an Independent — said during an interview Sunday that he wouldn't run unless he thought he could win.
Sanders says he is concerned that Clinton and the Republican candidates who oppose her won't take on what he calls the "big money interests" who control the economy.
The 73-year-old Sanders has been a member of Congress for 24 years.
