Ex-Sinema aides lobbied for corporations looking to affect Biden

Two of Sen. Kyrsten Sinema’s former aides have recently lobbied for corporate giants that have sought to influence President Joe Biden’s agenda.

The ex-staffers worked on behalf of financial giant HSBC, Starbucks, investment firm C5 Capital, Duke Energy, lead and copper producer Doe Run Company and mining concern ​Broken Hill Proprietary, according to registration and quarterly reports.

The two people, Kate Gonzales and Alyssa Marois, appear to be rare examples of former Sinema staffers registered to lobby the federal government. Their position makes them particularly valuable to their clients since their former boss, an Arizona Democrat, is a pivotal vote in a Senate split 50-50 by party.

Sinema and conservative Democratic Sen. Joe Manchin, D-W.V., have played a vital role in the Democratic-held Senate in the past year as their party tries to pass bills including Biden’s Build Back Better Act with a simple majority. A single Democratic defection can sink major legislation.

Sinema has not committed to voting for the Build Back Better Act, Biden’s $1.75 trillion social and climate spending package. As Democrats negotiated the Build Back Better Act last year, Sinema shot down Biden’s proposal to raise the corporate tax rate to at least 25% from 21%. She backed more complicated plans for a minimum corporate tax and a surtax on the wealthiest individuals.

The centrist has also rankled members of her party on other issues: while she supports an elections reform bill the Senate plans to take up this week, she has opposed eliminating the filibuster to pass the controversial bill in the face of unified Republican efforts to block it.

Sinema helped to write and voted for Biden’s recently signed $1 trillion infrastructure law. For his part, Manchin has opposed the Build Back Better plan and making any changes to filibuster rules.

Gonzales, one of the former Sinema aides turned lobbyists, must wait a year before being able to lobby Sinema’s office, according to Senate rules. Gonzales’ LinkedIn page says she left Sinema’s office in April after five months as a policy advisor.

Her previous experience includes just over a year as a legislative aide for Sinema. Gonzales could still lobby other lawmakers and their staffs.

Representatives for HSBC and Sinema’s office declined to comment. Gonzales, Marois and the other current clients mentioned in this story did not return requests for comment before publication.

Marois, who worked for Sinema’s office while she was in the House of Representatives, became the senior vice president of public affairs at HSBC last year. The company announced her hiring in late September. She was previously a lobbyist for Wall Street titan J.P. Morgan Chase.
