From an Eleanor Eagan Jeff Hauser analysis of independent agencies:

Finally, the plight of the Federal Election Commission (FEC) is an example of how Trump’s slowdown can exacerbate pre-existing threats to the public good. All of the commissioners are serving expired terms, a problem with its roots in pre-Trump Washington dysfunction. As no more than three members of the same party can be on the commission at any one time, the six member commission is generally split evenly between Democrats and Republicans. At the moment, however, there is only one Democratic commissioner while there are two Republican commissioners and an Independent often but not always aligned with the Democratic Commissioner. This 2-1-1 split has lead to outcomes such as the FEC deciding by a 3-1 vote to “not investigate President Donald Trump’s political campaign for enriching his businesses after considering a complaint from a liberal watchdog group, which alleged that Trump’s boasting about his hotels and use of his private jets constituted a violation of campaign law.” Weintraub has also been notably more concerned than Walther with foreign interference in US elections.
