The obvious assumption is that Q is with POTUS, but my guess based on the original images Q has posted, his ability to view IP's, and references to NSA and MI, is that Q has access to POTUS' tweets prior to them going live. It only makes sense too. Imagine if someone gained access to his Twatter and posted something inflammatory, potentially causing an international crisis. That could never happen, so protective measures are obviously in place to act as a firewall.
