You may be thinking of that woman (an outspoken Trump-hater) in Arizona who put aquarium or similar quality bleach in her now dead husband’s beverage/food, all while blaming President Trump.
Last I checked on that story, she will be heading to trial for murder.
I thought it was aquarium stuff with quinine or something similar.
It was when Trump was saying Hydroxychloroquine was good and the left was losing their minds.
The woman said they both took it but then she was being investigated for murder?
Really convoluted mess as I recall.
