Senator Bernie Sanders at a town hall event in New York City, Jan. 5, 2016 Rick Kopstein

As the top lawyer for the Bernie Sanders campaign, Brad Deutsch has had a front-row seat to one of the most remarkable presidential elections in decades.

He also has an unusual practice, mixing political and communications law with advocacy on behalf of the country’s fledgling legal cannabis industry. His 125-lawyer firm, Garvey Schubert Barer, formally launched a cannabis industry practice in 2014, and Deutsch contributes to the firm’s Cannabis Business Blog.

But the same two topics—politics and pot—were mostly off-limits when Deutsch agreed to speak with The Am Law Daily on Tuesday, hours before Hillary Clinton defeated his client in the New York Democratic primary.

As Sanders slugged it out with Clinton in New York, Deutsch, 50, was in Las Vegas, preparing to moderate a conference panel on political advertising. In a phone interview, he declined to answer any questions on the campaign’s legal strategy, including about fresh allegations of Clinton fundraising violations or the potential for a contested Democratic Party convention. And though Sanders is the only presidential candidate to endorse marijuana legalization, Deutsch insisted that cannabis has never come up in his work for the campaign.

All in all, it’s been a busy week for Sanders on the legal front. On Monday, the campaign accused a joint fundraising committee for Clinton, the Democratic National Committee and nearly three dozen state Democratic parties of violating campaign finance laws. In a letter to DNC chair Debbie Wasserman Schultz, Deutsch claimed that that the Hillary Victory Fund may be allowing the Clinton campaign to exceed limits on legal donations, and may also be improperly subsidizing her expenses.

His partner at Garvey Schubert Barer, Claire Hawkins, also made headlines on Monday for demanding that a company stop using the campaign’s intellectual property in “Bernie Is My Comrade” T-shirts and other merchandise.

Deutsch, based in Washington, D.C., was hired by the Sanders campaign as it was gearing up last April. Since then, his firm worked to contain the fallout after a , and Deutsch successfully fought to win 17-year-olds the right to vote in the Ohio primary. He and his firm also handled IP aspects of Ben & Jerry’s “Bernie’s Yearning” ice cream launch.

Deutsch, pictured right, said Tuesday that he was referred to Sanders by a colleague, whom he declined to name. In March alone, Federal Election Commission filings show that the Sanders campaign paid $79,886.84 to Garvey Schubert Barer for its services.

“I was just at the right place at the right time,” he said.

Beyond the campaign, Deutsch said he represents “a range of House and Senate candidates, as well as corporations and their political committees.” He also advises NORML, a nonprofit lobbying organization aimed at marijuana law reform.

He was recruited to join the communications practice at Garvey Schubert Barer in 2014. Before that, he spent more than a decade at the Federal Election Commission, including as chief counsel to Commissioner Steven Walther. Early in his career, Deutsch was an associate at Hogan & Hartson, where he frequently worked on matters involving the Federal Communications Commission. (Hogan & Hartson merged with British firm Lovells in 2010 to form Am Law 100 firm Hogan Lovells.)

Deutsch’s FCC practice has continued at Garvey Schubert Barer. Among other matters, he was recently part of the team that helped Pandora Media Inc. gain the agency’s approval of its acquisition of radio station KXMZ.
