US Congressman Scott Perry said that USA has financed Boko Haram and other similar groups (remember how Pentagon and CIA independently backed different terrorist groups in Syria, that even fought each other?)
Scott Perry didn't present any evidence for those claims. Ideologically he is opposed to the humanitarian work USAID does around the world, and he cheered as Elon Musk dismantled the agency.
Perry was also one of the key figures in the criminal conspiracy trying to overturn the result of the 2020 election and overthrow the US government to install Donald Trump as a dictator based on a series of outrageous lies. If Trump hadn't been elected again in 2024, interrupting the relevant investigations, there's a decent chance Perry would be either on trial or perhaps even already convicted for his crimes (conscious of his guilt, he directly asked Trump for a pardon).
I wouldn't consider any claims he makes credible without some corroborating evidence.
I don't really give a fuck what he claims.
