The father of fallen soldier Sgt. Roshain Brooks called out President Donald Trump on Wednesday for claiming that he “called every family of someone who’s died,” when he never got a condolence call from the POTUS following his son’s death on Aug. 13 due to an artillery blast.

Trump had recently boasted that he was better than his predecessors and compared himself with former President Barack Obama as he makes it point to call the family member of every soldier who died in battle. However, Trump’s claim quickly fell apart when Uvince Brooks, 58, told New York Daily News that he was still waiting for such a call from the president.

“This guy is a liar,” Brooks said. “When I heard what he said, it got me so mad. I called my daughter and said, ‘Can you teach me to tweet? I wanna tweet at Trump.’ That’s the only way to reach him.”

The grieving father said that Trump was worse than any of the leaders who have graced the Oval Office. “He’s lying. He didn’t contact us,” Brooks said. “Nobody from the White House cares about my family and our grief. If they cared, they would say something to us. I’m so upset. He’s a damn disgrace to the White House. I’ve been here for 17 years. Presidents George Bush and Obama, none of them behaved like this guy. This guy is a damn lunatic.”

Brooks added that Trump could not apprehend what it was like to lose a son and how one goes into an unending grieving process following the tragedy.

“When I listen to what the President is saying, I want to fight,” he said. "We can't sleep at night. My wife can't sleep, and I have to stay up with her. So to hear (Trump) coming out, lying like that, it makes it even worse. From the day that guy was born, he was a hero to me. He was my first born, my right eye. He was everything to me. He's a hero. We did a lot of things together. Losing him was almost like losing myself.”

Brooks’ comments came in the wake of latest reports alleging that there are other families of fallen soldiers who were made false promises by Trump. For example, Chris Baldridge, the father of Army corporal Dillon Baldridge, who was killed by an Afghan police officer on June 10 was promised $25,000 in compensation from the POTUS – a sum of money that is yet to reach the frustrated father.

While Baldridge’s ex-wife received a generous amount of $100,000 as death gratuity, while all the grieving father received was a condolence letter. “I opened it up and read it,” he said, “and I was hoping to see a check in there, to be honest. I know it was kind of far-fetched thinking. But I was like, ‘Damn, no check.’ Just a letter saying ‘I'm sorry.’”

According to the Washington Post, the White House has confirmed that the check for $25,000 was sent on Oct. 18. The exact status of the check is yet unknown.

“The check has been sent,” White House spokeswoman Lindsay Walters said. “It’s disgusting that the media is taking something that should be recognized as a generous and sincere gesture, made privately by the President, and using it to advance the media's biased agenda.”

In related news, Rep. Frederica Wilson (D-FL), who had reportedly bore witness to Trump causing the pregnant widow of fallen soldier La David Johnson to break down in tears after he told her, “He knew what he signed up for,” received multiple threatening phone calls on Wednesday, CBS News reported. Wilson’s office has reported the phone calls to Capitol Police, Miami Garden Police and the threat division of the U.S. House of Representatives.

The congresswoman told reporters on Tuesday that she overheard Trump’s so-called consoling phone call to the widow Myeshia Johnson where the president used insensitive remarks. After the news went public, Trump took to Twitter vehemently denying the reports and calling the congresswoman a liar.
