You want your logline and script to stand out from the others but for the right reasons. I agree with what DPG and Richiev said before. Your logline is too long, but still too vague and also incorrect.
Too long, because usually logline should be less than 35 words. Yours is way above that count.
Too vague, as it does not say why the CIA want them dead. Who are those people? Obviously former military personnel, but then why was he discharged? What kind of discharge: honourable, dishonourable, on medical ground? What are they to stop the chase? I am assuming that they will not just hide forever.
Incorrect as the CIA is not legally authorised to operate on US soil. DHS, NSA, FBI can. So if you absolutely want to use the CIA, indicate that they are rogue agents. If you don't people will just assume that you didn't and haven't made your homework. Straight away, you're projecting a bad image to your script reviewer.
Due to the lack of info, I have forced to invent things in your logline rewrite.
When former navy seals stumble on a plot to frame them for the murder of an anti establishment presidential candidate, they must race across Miami to prevent her assassination by rogue CIA agents.
