U.S. Trade Representative Katherine Tai is working to repair her relationship with National Security Adviser Jake Sullivan after a Situation Room confrontation in which she accused him — in front of colleagues — of undermining her in the press, people familiar with the matter tell Axios…

Witnesses, including Commerce Secretary Gina Raimondo, looked stunned, sources familiar with the matter told Axios. Raimondo’s office declined to comment.

Stories about the confrontation, as well as broader tensions between USTR and the NSC, have since been circulating throughout the West Wing.

The intrigue: Sources said Tai was outraged by stories during September in Bloomberg and The Wall Street Journal reporting the administration was considering investigating Chinese industrial subsidies under Section 301, which could lead to new tariffs.
