Delaware state Sen. Sarah McBride has been elected to the U.S. House and will become the first openly transgender person to serve in Congress. McBride easily defeated Republican John Whalen III on Tuesday in the race for Delaware’s lone House seat.

The young Democratic Party representative made history when she won the elections for the House of Representatives in the state of Delaware.

McBride, meanwhile, has established a national profile as an LGBTQ activist and raised more than $3 million in campaign contributions from around the country. She achieved national recognition at the 2016 Democratic National Convention as the first openly transgender person to address a major party convention in the United States.
