The Aug. 4 letter from the attorneys general was organized by Arizona Attorney General Mark Brnovich, who in a news release of that date said he led the coalition of the 19 states in "calling out its practices of putting leftist politics above investors' interests and returns."
Since that letter, BlackRock came under further fire when on Aug. 24, Texas Comptroller Glenn Hegar included BlackRock on a list of 10 financial companies he has determined "boycott energy companies."
Mr. Hegar is charged with implementing a 2021 state law that restricts the state's pension funds and other state entities from investing in companies that divest from fossil fuels.
In her letter Wednesday, Ms. Blass reiterated prior comments from the company that it "does not boycott energy companies or any other sector or industry."
"As we have noted previously, BlackRock, on behalf of our clients, is among the largest investors in public energy companies, and has hundreds of billions of dollars invested in these companies globally, with approximately $170 billion invested in U.S. companies," she said.
She continued to say that the manager has invested in a broad range of global energy ventures, which "involve a diverse mix of energy sources, including natural gas and renewable sources of energy, as well as decarbonization technology that needs capital to scale. Such a significant investment in, and cooperation with, energy industry companies, ranging from international corporations to entities dedicated to serving local communities in your states, is completely at odds with any notion of a boycott."
Ken Paxton, Texas attorney general, was one of the signatories of the Aug. 4 letter.
