11-year-old Miah Cerrillo, a fourth grader who covered herself in blood and played dead in order to survive, is among those taking the stand.

Other survivors, as well as the families of victims, are also in Washington, D.C. are calling for change.

“My mother’s life mattered, and your actions here today would tell us how much it matters to you,” said Garnell Whitfield Jr., the son of a shooting victim in Buffalo, New York.

Wednesday’s hearings come one day after Academy Award-winning actor Matthew McConaughey appeared at the White House, and called on Congress to pass gun control legislation following last month’s shooting in his hometown. He specifically called on Congress to bolster background checks for gun purchases and raise the minimum age to purchase an AR-15-style rifle to 21 from 18.

Two sources tell ABC News Senate Minority Leader Mitch McConnell has privately expressed openness to raising the age to buy a semi automatic rifle from 18 to 21.

That report comes as a group of bipartisan senators aim to have a compromise on proposals ready by the end of the week.
