Puerto Rico's most famous openly gay singer on Wednesday called on lawmakers to approve a gay rights law.

Ricky Martin called for House members to approve bill No. 238, which seeks to prohibit discrimination based on sexual orientation and gender identity. The measure cleared the Puerto Rican Senate last week but a group of lawmakers in the lower chamber came out against it on Monday.

“The rights of homosexual people are human rights and human rights are for everyone,” Martin said in the letter released by his representative in San Juan.

He added that lawmakers have a responsibility to end the violence, hatred and discrimination against the LGBT community.

In a tweet to his nearly 9 million followers, Martin urged fans to contact five representatives on Facebook about the proposed bill.

“Tomorrow they'll vote and we have to mobilize,” he said in Spanish.
