Last night, at the 13th Annual National Dinner of the Human Rights Campaign in Washington, DC, Lady Gaga performed John Lennon's "Imagine."
She tweeted, "So proud to be apart of HRC event, our brilliant president has taken a stand against hatred/inequality in the gay community. It was a historical night. Now is the time for you to get out of your beds, pack your bags, and meet me in DC to march 2moro for equality."
Thousands of activists are expected to gather today for a rally march, which will be organized by HRC and other groups, to call for lesbian, gay, bisexual and transgender rights.
