Passed by the Senate February 28, 2025.

Passed by the House March 27, 2025.

Approved by the Governor April 4, 2025, with the exception of certain items that were vetoed.

Filed in Office of Secretary of State April 7, 2025.

Note: Governor's explanation of partial veto is as follows:

"I am returning herewith, without my approval as to Section 2, Senate Bill No. 5577 entitled:

"AN ACT Relating to medicaid coverage for HIV antiviral drugs."

The funding for the medications addressed in this bill are already covered in the Health Care Authority's base expenditures. Accordingly, there will be no gap in coverage, so there is no need for an emergency clause.

For these reasons I have vetoed Section 2 of Senate Bill No. 5577.

With the exception of Section 2, Senate Bill No. 5577 is approved."
