"This is on every congressperson who said in '13: 'There is simply nothing we could do,'" Nelba Marquez-Greene wrote.
She was also critical of those who blamed the current political climate for the mass violence.
"Oh, please. Newtown happened well before Trump was elected. We need sensible gun legislation and we need it now," she tweeted.
Marquez-Greene lost her 6-year-old daughter when a gunman opened fire inside Sandy Hook Elementary School in Newtown, Connecticut in December 2012,
26 people, including 20 first graders and six adult school staff members, were killed by the gunman, who then killed himself.

You don’t recover from this- as a mother, brother, father. You manage. But there is no recovery. I am heartbroken. #LasVegas #Newtown

For that person or any person to blame media for this is reprehensible and irresponsible. Blame your congress. #Newtown https://t.co/UekZg5Mgri

Every day, I am stunned by the level of trauma (direct or vicarious) congress is willing to make us suffer through. #Newtown #LasVegas

Their lack of courage and/or ability to take meaningful action on issues that most matter: healthcare, violence, climate, etc is outrageous

Many people. Five years later they still contact you. It’s bad and no one wants to talk about. As a victim? I have to. #Newtown #LasVegas https://t.co/vEgJjJPPWS

As a mom who had to bury a child- I could care less about perp color. But how come we never talk about angry White men w/guns? #Newtown
— Nelba Márquez-Greene (@Nelba_MG) October 2, 2017
How come we only want to talk when it fits our own narrative? Please. Help mothers keep children safe from gunviolence. #lasvegas #Newtown

I just don’t want any more moms to live like I do. Yes. I’ve managed to do amazing things. But honestly? I battle grief related 1/2

Anxiety, depression, PTSD- daily. Losing a loved one like this is a death sentence. We move forward for our son.

Is this what we are saying to American citizens they have to accept as normal? 91 people per day? #Newtown #LasVegas

I will also say this: I lost Ana in Newtown which means even though we aren’t white I had the sympathy of the world. #Newtown #LasVegas
— Nelba Márquez-Greene (@Nelba_MG) October 2, 2017
I know so many mothers navigating this world of grief and trauma blindly because their kids died in urban centers& there is no sympathy.
— Nelba Márquez-Greene (@Nelba_MG) October 2, 2017
Guess what folks? Gun violence and grief hurt in EVERY zip code. In every color. Grieving mothers need your help. #LasVegas #Newtown

In America we value guns, flags & fake acts of patriotism over people, pain & real acts of courage. #LasVegas #TakeAKnee #EndGunViolence

Did you know u have congress people who rather than talk about gun legislation implied that we hadn’t prayed hard enough?#Newtown

There is no such thing as being in the wrong place at the wrong time when a 6 y.o. gets shot. There are only cowardly congresspeople.
