Bloomberg reports that contributions to the Rubio campaign from workers at the investment firm totaled $107,000 in the last quarter of 2015, up 50% from the previous two quarters.

Those donations to Rubio came as just two Goldman employees contributed a total of $2,950 to Bush, whose campaign is struggling. Since the early months of the 2016 race, employees have given a combined $773,000 to the Bush campaign, his leadership PAC, and his super-PAC.

The Des Moines Register poll ahead of Monday’s Iowa caucus pegged Rubio at 15% while Bush stood near the bottom with an estimated 2%.

Ted Cruz, who’s polling at 23% in Iowa and whose wife used to work at Goldman, has collected $52,000 from the donors at the firm.

The campaign for Democratic presidential frontrunner Hillary Clinton has taken in a total of $103,000 from Goldman contributors. The super PAC supporting her has received $100,000.

Donations from Goldman Sachs employees are noteworthy because the investment firm has ranked among the top 15 donors to candidates for federal office and their committees since 2001, Bloomberg reports.
