Ted Lieu, the caucus vice chair (outranks them all), was reported to be among them. He later denied it, saying he did not speak on the call. This was confirmed by a source familiar. Not sure what to make of that.
Other high-ranking and long-serving members like Beyer, Lofgren, Himes, and Larsen are said to have expressed doubts. Beyer issued a non-denial denial, saying he "supports the President".
