My guesses:

• The US Supreme Court will, at least to a degree, reverse course on Roe V. Wade
• I'm not sure what to guess on whether the US Supreme Court will do what former President Trump wants, as to blocking access, of the committee investigating the January 6 insurrection, to his records. If I have to guess, I'll guess they will impair access at least to some degree.

My logic is:
Conservatives, including the Trump administration, have spent most of the last two decades getting their majority in place. Roe V. Wade has been used as a sort of acid test in the vetting process (no matter whether it is explicitly stated) and while it is not possible to know with certainty how any justice will rule, I think the nominators did their homework on this point as strongly as on any. I think it would be naive to harbor too much hope that many or any of them will seek to protect Roe V. Wade.

As to protecting the relevant White House records from access by the committee:
I'm guessing nominees were put into place probably with an understanding or educated guess that they would vote with Trump's perceived desires when the time came. Maybe it would be illegal to try to get an agreement, but based on past Trump administration behavior, it seems a reasonable guess that from that Administration's point of view, the nomination would not have happened if they did not expect what they have called "loyalty" to Trump, over loyalty to the job or to the Constitution. There have been instances in history when Supreme Court Justices have defied expectations (if I recall) and it would not be shocking for my guess to be wrong. Further, it could be argued that even moderate Justices may try to temper the ask on the part of the committee, not so much in the interests of the former President, but out of concern for any chilling impact on conduct in the office in the future. I don't know what will happen here, but a year ago around this time it seemed like the former President wanted to get his argument over the supposedly stolen election to the Supreme Court, and I think it was because he thought they would be somewhat sympathetic, not on the merits, but out of loyalty. He's probably thinking similarly here. We'll see what happens.
