Ellen L. Weintraub is an American attorney who has served as Commissioner (since December 9, 2002) and Chair (most recently since January 1, 2025) of the Federal Election Commission.

Weintraub subsequently returned to private practice as counsel at Perkins Coie LLP, where she was a member of its Political Law Group.

[8] In March 2016, following the Supreme Court decision on Citizens United v. FEC, Weintraub published an op-ed in the New York Times where she expressed the dangers of foreign national interests - by way of corporations, who most likely have international shareholders - intruding upon American politics via campaigning.

[11] “The scheme the President of the United States alleges would constitute thousands of felony criminal offences under New Hampshire law,” Weintraub said in a statement printed on FEC letterhead.

[13][14] Weintraub subsequently defended her actions and maintained that the alleged fraud would constitute a violation of federal campaign finance laws, which is germane to her position as a FEC commissioner.

[16][17] During 2017, Weintraub championed greater disclosure of political ads on the internet, and helped move the FEC to open a rulemaking on the matter with bipartisan support.

Commenting "There’s a legal way to replace FEC commissioners-this isn’t it", Weintraub later told reporters that she does not recognize her purported dismissal and intends to remain in office.
