"Serving on a jury is one of America's most cherished civic duties," she said. "It is unjust to exclude a particular group of people from participating in civil society because of whom they love or what they look like.
"The federal government already prohibits juror discrimination on the basis of race, color, religion, sex, national origin and economic status, and as we pursue greater equality for all Americans, I believe LGBT Americans should also be free from juror discrimination."

Davis's bill was proposed just days before President Obama delivered his second inaugural address, in which he called for ongoing work to ensure lesbian, gay, bisexual and transgender people are afforded equal rights.
"Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, for if we are truly created equal, then surely the love we commit to one another must be equal as well," Obama said Monday.
Davis's bill was introduced with 14 co-sponsors, including freshman Rep. Grace Meng (D-N.Y.).
