A staff member of a Mississippi Democratic congressman has reportedly been fired after saying she wished shooter Thomas Crooks had 'better aim' to take Donald Trump's life. 

On Saturday evening, July 13, shortly after Thomas Matthew Crooks, 20, attempted to assassinate the former president during a rally in Pennsylvania, Jacqueline Marsaw, the field director for Mississippi Congressman Bennie G. Thompson shared a vile post on Facebook about the attack. 

Democratic congressman Marsaw, 61, the president and vice president of a local NAACP in Natchez, Mississippi, has since deleted the post and her account, but screenshots have been shared across social media. 

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.'

In a follow-up post, she said: 'That's what your hate speech got you!!' 

Warsaw has since been fired from her position by Mississippi Congressman Bennie G. Thompson.

"I was made aware of a post made by a staff member, and she is no longer in my employment", Thompson said

A member of the crowd was killed in the deadly shooting, while two others who were wounded are in a critical condition. All three are males, according to law enforcement officials. 

After Trump was shot, the Secret Service swarmed around the 45th US President as piercing screams were heard from the MAGA crowd.

He then got to his feet with blood down his cheek and raised his fist in the air while the audience shouted 'USA' as he was dragged off stage.

Trump was taken to the hospital for treatment before being later released.
