A Monsanto Co. lobbyist, who is seen as Hillary Clinton’s “main man” in Iowa, was among the top financial bundlers of contributions to benefit Hillary Clinton’s run for the White House in the most recent quarter, new Federal Election Commission reports show.

Jerry Crawford of the Crawford & Mauro Law Firm in Des Moines, Iowa, bundled $151,727 for the campaign over the quarter ending Dec. 31, FEC documents show. Crawford is senior adviser to Clinton’s 2016 presidential campaign and was the Midwest Co-Chair of the Hillary Clinton for President Campaign in 2007-08. His firm listed Monsanto as a client in the most recent quarter, reporting $60,000 in lobbying income from Monsanto. Monsanto is known as one of the nation’s most powerful corporations, and is currently engaged in a range of public policy debates over regulation of its genetically modified crops and top herbicide product, Roundup.

Another Monsanto lobbyist, Steve Elmendorf, bundled $20,295 in contributions for the Hillary for America organization during the quarter, FEC documents show. Elmendorf also does work for the Grocery Manufacturers Association, which has been battling against mandatory labeling laws for foods made with GMOs.

The total of all bundlers for Clinton campaign over the quarter was $716,981, according to the FEC documents.

Clinton is widely seen as a friend to genetically engineered crop technology and agrichemical interests, while her chief competitor for the Democratic nomination, Bernie Sanders, has been a supporter of mandatory GMO labeling.
