I remember reading something more specific at the time, but I cannot find it on twitter. I remember reading some kind of statement from him. It is lost under so much other information and frankly, I cannot be arsed to find the specific statement.
However, here you go as it was also brought up in the past weeks as something Moira Deeming 'should have known':

This article is from the 9th November 2022 and states :
"Chris Barcenas, who also organized the rally and is another former Proud Boy turned Miami-Dade GOP committee member"
The Let Women Speak rally was 5th November 2022, I doubt that he left the group within the four days between.
I believe that Chris Barcenas has political aims, as he was then and is now a member of the Republican Committee. He is now on the Miami-Dade Republican Executive Committee. Did he use that rally for his own political benefit? Quite likely. However, it pays to focus on the facts and the accusations and when those accusations were made.
