The MSM isn't drawing attention to it because the CIA doesn't want them to since the CIA controls the MSM's message.
This has two possible reasons:
1) The hero, Kate Mazzochetti, that 'saved' Trump was actually a CIA operative that was trying to get close to Trump.. she wanted to 'hug' him. Really she wanted to kill our President.
2) the CIA doesn't want people knowing that there have been attempts on Trump's life because they don't want to get exposed
