Since losing the presidential race, Hillary Clinton has kept a low profile. But that may be changing.

In one of her first major public appearances since the election, Clinton will be the featured speaker at a Houston luncheon on April 7 to benefit Annie's List, an organization that works to elect women to public office, officials announced on Monday. The event, which will honor Houston attorney Amber Anderson Mostyn, will take place at the Marriott Marquis Hotel.

The noon luncheon will be preceded by a panel titled "Turning Harris County Blue." Clinton carried Harris County by a 12 percent margin over Donald Trump in the 2016 presidential race.

Annie's List organizers point out that although women comprise nearly half of the state's population, men hold 80 percent of the seats in the Texas legislature and in Harris County, men hold 70 percent of all public offices.

"Secretary Clinton and Annie's List understand that elections matter. This is why we are thrilled she's giving her time and voice to spend the day with Annie's List to help us build our war chest to elect more Texas women," Annie's List executive director Patsy Woods Martin said in a statement.

The luncheon is close to selling out, organizers said, but some tables are available, ranging from $5,000 to $25,000.
