Each lawmaker gets one ticket to invite a guest to the address, and guests are seated in the gallery above the House floor.
According to NBC some lawmakers are taking an even further step and bringing sexual assault survivors as their guests to the address by Trump, who has been accused of sexual misconduct by at least 19 women.
Speier said the Democratic Women's Working Group, which includes all of the female House members, was encouraging lawmakers from both sides of the aisle to wear black to the event, and that support is very high.
The wave of allegations of sexual misconduct have already resulted in resignations from members of Congress, and have sparked debates about the unique rules that Congress has established for itself when it comes to sexual harassment or assault charges.
Last month, almost 60 female Democratic lawmakers demanded that Congress investigate allegations of sexual misconduct against Trump.
The lawmaker, who asked not to be identified, told NBC Democrats would be "no better" than Republicans if they made a decision to "retaliate" at the State of the Union address. Trump has denied all those claims. Last year, female Democrats chose to wear white in support of women's rights, when President Trump spoke to a joint session of Congress for the first time.
Some 20 women have publicly accused Trump of misconduct.
The annual message presented by the USA president to a joint session of the United States Congress typically includes a budget message and economic report of the nation, while also providing the president with an opportunity to outline their legislative agenda and national priorities for the year ahead.
