Herschel Walker's influencer son castigated his father's Senate campaign following his Tuesday loss.
Christian Walker told Buzzfeed on Wednesday that his father ran a "dumb" campaign.
He also rejected suggestions that his criticism contributed to his father's loss.
Herschel Walker's outspoken son unleashed a storm of criticism against his father this week following the conclusion of the former athlete's failed Senate campaign, comparing the Republican candidate to an unprepared student.
"I felt like oftentimes he sounded like a kid who was giving a book report presentation and didn't read the book, like he didn't feel like he was properly studying," Christian Walker, 23, told Buzzfeed on Wednesday.
The younger Walker's sit-down interview with the outlet came just hours after Democratic Sen. Raphael Warnock defeated his father in Georgia's Senate runoff election on Tuesday night. Herschel Walker's campaign attempted to fend off mounting controversy in recent months, including allegations that he paid for two women to have abortions despite his stringent stance against abortion access.
"There is no quality as a candidate," Christian Walker said of his father. "He doesn't know what he's talking about. His past is insane. There was no quality there. It was ridiculous."
The young right-wing influencer had previously addressed his father's unorthodox campaign, castigating the former NFL player in a series of tweets and videos earlier this fall after The Daily Beast reported the abortion allegations.
"I don't care about someone who has a bad past and takes accountability. But how DARE YOU LIE and act as though you're some 'moral, Christian, upright man.' You've lived a life of DESTROYING other people's lives. How dare you," he tweeted in early October.
Christian Walker told Buzzfeed that he begged his father not to run for political office, citing his checkered past, which includes his own mother's allegations that Herschel was violent toward her and recent allegations that he fathered "secret" children.
"Please do not do this to us and please don't do this yourself," Christian Walker said he told his father ahead of the campaign. "It's a nasty thing. You have a good reputation. Nobody really knows about your past."
Herschel Walker repeatedly denied both the abortion and secret children allegations on the trail. A spokesperson for his Senate campaign did not immediately respond to Insider's request for comment.
The Wednesday Buzzfeed article followed Christian Walker's own social media comments on his father's loss. The younger Walker tweeted Tuesday that former President Donald Trump repeatedly called his father "demanding" that he run in the runoff race, even though "everyone with a brain" begged him not to.
Christian Walker also rejected suggestions that his comments throughout the campaign contributed to his father's loss.
"Did I give any new information? Literally, I did not. I said nothing new. We all already knew all of the scandals," Christian Walker said. "So no, they blew the campaign up by running a dumb campaign. I did nothing."
