Officials used Twitter Wednesday afternoon to mark the ruling of U.S. District Chief Judge Vaughn R. Walker striking down California's Proposition 8, which banned gay marriage in the state.

"The evidence shows conclusively that moral and religious views form the only basis for a belief that same-sex couples are different from opposite-sex couples," the decision read.

House Speaker Nancy Pelosi (D-Calif.) said:

Very joyful court ruled against #prop8, it is a stain upon the CA Constitution. All families must be treated equally!
