Glenn Simpson and Peter Fritsch, co-founders of Fusion GPS, joined Andrea Mitchell and defended their investigation into then-candidate Donald Trump’s contacts with Russia in 2015. Simpson says that there was no Democratic conspiracy to frame Trump, and that the allegation that Christopher Steele’s dossier about Trump’s contacts in Russia had originated from Ukraine is 'another phony conspiracy theory.'
