Actress Amanda Seales posted an outrageous video online explaining why she thinks the attempted assassination of Donald Trump was staged.

The former president, 78, survived the attempt on his life when the bullet missed him by less than an inch on Saturday afternoon, at a rally in Butler, Pennsylvania.

Corey Comperatore, the retired fire chief of Buffalo Township, was killed in the shooting and two others were taken to hospital in a critical condition.

Ridiculous conspiracy theories about the assassination attempt have spewed online, including from HBO's Insecure actress Amanda Seales who posted a video claiming the attack was staged.

'That sh** was more staged than a Tyler Perry production of Madea Runs for President,' Seales said.

'I lived in Harlem long enough to know that gunshots do not sound like making popcorn on the stove.'

Video captured the horrifying moment the shooter opened fire and the 78-year-old dropped to the floor, before four Secret Service agents raced to the stage and dove on top of the former president.

Stunning images showed Trump cowered on the floor as agents protected him, with blood dripping down his cheek.

'Where did the blood come from? So in theater, in movies they have what's called blood pellets. People use them for Halloween,' Seales claimed.

'It's basically a pellet of fake blood that's in your mouth and when you crush it the blood comes out.

'To be frank, small hands Trump would not respond by raising his fist in the air triumphantly were an actual attempt made on his life.

'This was, I believe done to try to show his strength counter to Biden's fragility.'

A staff member of a Mississippi Democratic congressman was fired after she took to social media and said she wished the shooter had better aim. 

Jacqueline Marsaw, 61, the field director for Mississippi Congressman Bennie G. Thompson shared a vile post on Facebook about the attack.

She shared: 'I don't condone violence but please get some shooting lessons so you don't miss next time ooops that wasn't me talking.' 

Marsaw, the president and vice president of a local NAACP in Natchez, Mississippi, garnered attention of Republicans across the country. She has since deleted the post and her account, but screenshots have been reposted across social media. 

She has since been fired from her position. 'I was made aware of a post made by a staff member and she is no longer in my employment,' Thompson said.
