Via press release from Chad Griffin of Human Rights Campaign:
After careful consideration, HRC’s Public Policy Committee of the Board of Directors has taken the unprecedented step — a first in our 36-year history — of revoking an endorsement. [..]
Attacking someone because of her race and ethnicity is inexcusable for anyone, but especially for a sitting U.S. Senator. The diversity of our movement is our greatest strength, and Senator Kirk’s remarks were an affront to our most fundamental values. We have therefore voted to endorse Congresswoman Tammy Duckworth, who has been a strong LGBTQ ally in the House of Representatives, and HRC will contribute the maximum amount to her campaign. We look forward to working with her in the Senate to secure full federal equality for all LGBTQ Americans.
