After the FBI identified Donald Trump's shooter as Thomas Matthew Crooks, a lot of information and disinformation have surfaced but there are more questions unanswered even 36 hours after the assassination attempt on Trump. Crooks acted alone and used his father's AR-15-style rifle to shoot at Trump at the Pennsylvania rally. The bullets grazed Trump's ear while Crooks was shot dead.

What was Crook's motive?

The motive of the shooter is not yet known. The family history, upbringing of the 20-year-old did not indicate anything which could be linked to the assassination bid. On the contrary, Crooks was registered as a Republican. But he also donated $15 to a Democratic project.

How did the Secret Service security breach take place?

Crooks shot at Trump from about 150 yards away from a rooftop. Reports claimed those who attended the rally raised alarm about suspicious movements on the rooftop but it's not clear why the Secret Service did not secure the area.

Was Donald Trump the only target?

The firearm reportedly belonged to Crooks' father and he was a lone-wolf attacker but it is not yet known what else the shooter had planned. Authorities reported finding explosives — including an IED, or improvised explosive device — inside a car driven by Crooks that was located near the Trump rally. Additionally, materials for making bombs were found inside Crooks’ home, AP reported.

What's next: Donald Trump rewrites RNC speech for Thursday

Surviving the shot, Donald Trump emerged as defiant with prominent figures openly declaring their support to the Republican candidate (presumptive). Trump has reportedly rewritten his speech for the RNC convention where he would officially be declared as the Republican candidate. Axios reported that Trump will be delivering a different speech than what he had earlier prepared -- a one of a kind speech targeting Biden.
