BOSTON (AP) — U.S. Sen. Elizabeth Warren is raking in millions in campaign donations as she gears up for a re-election bid next year.

According to Warren's latest campaign finance reports, the Massachusetts Democrat took in a hefty $5.9 million in campaign contributions from January 2015 through the end of 2016.

Contributions to Warren spiked in the final three months of last year, when she took in more than $1 million. That period from Oct. 1 through the end of December included the election of Republican President Donald Trump.

Nearly all of Warren's contribution came from individual supporters, with just $34,000 from political action committees and other groups.

Warren ended 2016 with $4.8 million left in her campaign account. She began the two-year period with just over $1.6 million in cash on hand.
