Democratic Sen. Heidi Heitkamp (N.D.) received nearly twice as much money from Goldman Sachs bankers in New York as from individuals in her home state of North Dakota over the past three months, according to her campaign's most recent filing.

Heitkamp, currently gearing up to run for reelection in a state President Trump carried by 36 percent, was heavily reliant on sources outside North Dakota during the last fundraising quarter, during which only $21,318 of the $739,218 raised came from North Dakotans.

Nearly twice as much money—$39,600—came from employees of financial giant Goldman Sachs alone, including a maximum contribution from Harvey Schwartz, the firm's president.

Also outpacing North Dakotans were New Yorkers, who supplied $191,408 to Heitkamp, and Californians, who supplied $124,452.

Overall, the $717,900 Heitkamp received from donors outside the state accounted for more than 97 percent of its fundraising during the quarter.

Heitkamp earlier this year attacked the idea that "billionaires outside North Dakota who don't know anything about our state" have an impact on its elections.

Heitkamp's campaign did not respond to inquiries into its fundraising report.

Republicans are seizing on the lack of money Heitkamp received from North Dakota, saying it is an indication of where her "loyalty lies."

"Heidi Heitkamp's campaign cash shows her loyalty lies with liberals in Washington, Los Angeles, and New York City rather than hardworking North Dakotans," said Michael McAdams, a spokesman for the National Republican Senatorial Committee. "It's clear Heitkamp would rather cozy up to out-of-state millionaires than represent North Dakota's interests."

Heitkamp currently has just over $3.7 million in cash on hand as she enters her reelection fight.
