Sullivan & Cromwell partner Michael DeSombre in Hong Kong, the Trump administration’s nominee to be U.S. ambassador to Thailand, reported earning more than $4 million from the firm and vowed to resign from various political groups if he is confirmed, according to new disclosures that were filed as part of his confirmation proceeding.

DeSombre’s newly filed financial disclosure and ethics agreement, mandatory submissions for many executive branch nominees, reveal a peek at the Am Law 100 firm’s partner compensation scheme. DeSombre, who joined Sullivan & Cromwell in 1995, estimated the value of his capital account at between $500,000 and $1 million, and he said he would receive a pro rata partnership share for legal services performed in 2018 and 2019.
