Senate lawmakers voted Friday to advance a measure to restrict bathroom use for transgender Texans.

Senate Bill 3 was proposed by Senate Lois Kolkhorst which also prohibits the use of showers in certain facilities for transgender individuals.

The bill states that a person in a government building or public school must use the bathroom based on the gender on their birth certificate

On Friday different groups lined up outside the state capital to express opposition toward the new bill.

Officials from large cities across the state have said that an estimated $66 million has already been lost in convention business. They say if the bill is enacted the state could loose up $1.4 billion.

The bill will now move forward toward the full Senate next week.
