The mother of Heather Heyer, the woman killed Saturday when a car rammed into a crowd of counterprotesters at a white nationalist rally in Charlottesville, Virginia, said she "will not" speak with President Donald Trump in the wake of her daughter's death.

“I have not and now I will not,” Susan Bro said in an interview with ABC News’ Robin Roberts today on “Good Morning America,” adding that she believes the first phone call to her from the White House came during her daughter’s public memorial service on Wednesday.

“The first call, it looked like actually came during the funeral. I didn’t even see that message,” said Bro. “There were three more frantic messages from press secretaries throughout the day and I didn’t know why.”

Bro, who had thanked Trump in a statement on Monday for his "words of comfort and for denouncing those who promote violence and hatred,” said she was recovering from the "exhaustion of the funeral" Wednesday and did not return the White House messages.

She said her opinion of Trump’s response changed after she had time to watch news coverage of the Charlottesville protests after laying Heyer, 32, to rest on Wednesday.

"I hadn’t really watched the news until last night and I’m not talking to the president now, I'm sorry, after what he said about my child," Bro explained. "It’s not that I saw somebody else’s tweets about him, I saw an actual clip of him at a press conference equating the protesters ... with the KKK and the white supremacists."

She continued, "You can’t wash this one away by shaking my hand and saying, ‘I’m sorry.’ I’m not forgiving for that."

When asked if there was anything she would want to say to Trump, Bro said, "Think before you speak."

Deputy White House press secretary Lindsay Walters told ABC News today in response to Bro's comments, "Our thoughts and prayers continue to be with her and her family."

The White House has not said whether they will continue to try and reach out to Bro.

Bro also sat down for an interview with ABC News on Thursday, during which she said she is hesitant, nearly one week after Heyer’s death, to speak to Trump or any politician.

"I understand that President Trump wants to speak with me… and it's not that I'm trying to be calloused, it's that I have no interest in speaking to politicians just to hear them say, 'I'm sorry,'" Bro told ABC News on Thursday. "If I felt like that's all they wanted to say, that would be different, but I feel like I'm wanted to be used for political agendas and I'm resistant to that."

Trump has come under heavy fire for his response to Saturday's "Unite the Right" rally, whose attendees included white nationalists, neo-Nazis and Ku Klux Klan members, and turned deadly after a car plowed into counterprotesters, killing Heyer and injuring 19 others.

In a news conference Tuesday at Trump Tower, Trump reiterated that "both sides" were to blame for the violence.

"I wasn't there that day, but I will tell you that I'm pretty sure that's the only person that ran people down with a car, so that level of violence didn't take place on both sides, that did not happen," Bro said Thursday of the crash that killed her daughter.

"I've heard it said that the murder of my daughter was part of making America great," Bro added. "The blood on the streets, is that what made America great? Attacking innocent people with a vehicle, is that what made America great?"

When asked if she had sympathy for the cause of the white nationalists, Bro said, "I don't know what their cause is. I haven't heard what's bothering them."
