I've just been through Peterson's Twitter (what a job that was, I didn't know anyone tweeted that frequently), he's got about 5 different tweets in the last 24 hours, some are straight retweets of other people's opinions and others are his own commentary, he seems to be careful what he's actually saying, but it comes across that he thinks the allegations against RB are convenient bullshit designed to bring down someone who might be onto something, and he also retweeted the one about how no one on Epstein's list ever got investigated because it didn't serve any purpose. Not sure if any of that counts as "offering support" though.
