If you haven't kept up with this whole thing.. looks like Grusch, Gillibrand, and Dr. Kirkpatrick (AARO) are going to have some sort of sit down soon. They've already stated they will have more hearings, both open to the public and closed
Dr. Kirkpatrick basically called Grusch a liar and how he was "disrespecting AARO" because he came forward to Congress in a LinkedIn post (weird format to state this). There's a weird thing with Grusch and Kirkpatrick where Grusch stated he told the director in a classified conversation some things, but was never followed up with or never formally interviewed
But as of now, whistle-blowers have no way of contacting AARO apparently... there is no phone number, there is no email address, there is no website, there is a single tweet from the department on Twitter.. And this is the organization that is supposed to be in charge of all UFO/UAP investigations even tho they haven't released any sort of public progress since their inception
