You're confused, which is my polite way of saying you're a troll.
Hint: Trump lies. Musk lies and despite their loud lies, there was no attempt to delay a rescue for political reasons.
Think about it (tall order, I know). What could be gained, back in June, from delaying a rescue, given that NASA, not the White House, had already been working with both SpaceX and Boeing (the latter being the guilty party), on various programs to service the ISS and the expected Lunar program.
In fact, the three parties (NASA, SpaceX and Boeing), agreed on the following plan in short order:
Sent SpaceX's Crew-9 to the IIS in September, but leave two empty seats. Crew-9 will remain tethered until mid February or so, and then the stranded astronauts will hitch a ride down, using the two empty seats.
Musk agreed to the plan and approved it, given that he's the SpaceX CEO.
The time table was necessitated by NASA's plan, as well as IIS plans and more importantly the stranded astronauts.
The return data was extended it by 3 weeks or so, to work on some issues.
So, Musk lied, Trump lied and you're one fat ass liar.
