Changes its position radically? The FBI came out saying it had moderate confidence in the lab leak theory in 2023, right in the middle of the Biden administration [0]. The DOE came out with their own assessment a few days earlier [1]. The CIA's position was hiterto "we're not yet sure", and now it's "we still aren't sure but we're leaning towards lab leak". That's not a radical shift, it's a very slight shift in the direction that other three-letter agencies have been leaning for years.
There were almost certainly some politics involved in the decision to release the report now, but it's not like the CIA were staunch advocates for zoonotic origins up until now, and again: Biden's FBI and DOE were already leaning this way!
