Concurrently with nuking Iran. A big miscalculation requires a big distraction as a counterweight.

To where it gets the least attention. He wants to do it when other news developments may drown it out.

Time will be after elections if he holds onto congressional Power. He HAS to lay low on Child Rape pre elections b/c He needs two more years of thievery, and HIS Congress will allow it. A pardon before elections, MAY turn even a few of his cult.
If he keeps power, he has no need for a base any longer and he will go nuclear with thievery and revenge, and his paid for pardons for the biggest scum on earth.
And then complete the disruption of our country as he promised Pooty for all his help.
Just my opinion.

If he pardons her now, she could walk out of prison and into a television studio and spill everything she knows. I suspect that her pardon will come on January 19, 2029 as Trump walks out the door, he will have no fear of political repercussions 5hen.

Trump is just waiting for maximum profit.

ALL the files-- under demand from angry public and Congress. He is definitely involved in something horrible, IMHO. No one fights that hard to avoid files being released that one is only tangentially involved in to that level. He's hiding something awful.

However, I still think he knows this would be political suicide to do before November.

regardless of the results. He'll be a lame duck with little political leverage left, so I'm guessing he'll go scorched earth on his fellow publicans as he scurries around to better position his post-office lavish lawsuit lifestyle and keep himself out of jail at the expense of idiots who think he's an ally.

He won't want her to be called to the NEW congress to testify! (after Jan 20th)

She's not a guy. Has he pardoned any women yet? Beyond the J6ers?
