Okay, to the people who think this is an actual threat that we need to combat: let's play devil's advocate here for a minute.
Let's say there is actually a threat of pirates in space. Why wouldn't the military or intelligence agencies be the ones briefing Congress about it and asking them to allocate funds into combating that threat? Why would Actual Human Being Ted Cruz need to do that for them? Could it actually be because he's full of shit and getting paid by military contractor lobbyists to make up shit to try to convince Congress to allocate more money towards the military industrial complex?
No, must be space pirates.
