Why did two Republican lawmakers appear at a conference organized by a Nazi sympathizer?

Freshman lawmaker Marjorie Taylor Greene shared a video in 2018 repeating an anti-Semitic conspiracy espoused by the gunman in the Pittsburgh synagogue massacre.

'As an avid supporter of QAnon, [Marjorie Taylor] Greene espouses anti-Semitic canards, such as placing blame on ‘the Rothschilds’ for recent wildfires in California,' the Conference of Presidents of Major American Jewish Organizations said.

Reps. Ilhan Omar and Rashida Tlaib and progressive Cori Bush in Missouri won their respective congressional races, as did Marjorie Taylor Greene in Georgia.
