Democrat Martin O'Malley has suspended his presidential campaign.
The former Maryland governor and Baltimore mayor never gained traction against rivals Hillary Clinton and Bernie Sanders.
Word about O'Malley's move comes from people familiar with his decision. They weren't authorized to discuss it publicly and requested anonymity.
O'Malley campaigned as a can-do chief executive who pushed through key parts of the Democratic agenda in Maryland. They included gun control, support for gay marriage and an increase in the minimum wage.
But O'Malley struggled to raise money and was polling in the single-digits for months despite campaigning actively in Iowa and New Hampshire.
