Josh Duggar's brother-in-law seemed to have had it with the eldest Duggar son after numerous scandals. Now, he's keen to convince his sister Anna Duggar to leave Josh for good.

Anna's brother Daniel Keller has reportedly expressed his sentiments over the latest scandal that Josh has gotten himself into. In a report on People, Kellar apparently poured out his feeling in a bible excerpt picture that Josh's younger sister, Jessa Seewald, posted earlier on Facebook.

Among the comments he purportedly wrote included doing everything he can to convince his sister to leave Josh. He also called Josh a "pig."

"I have been thinking of her and sick to my stomach for her for last few days," Kellar apparently wrote.

"I have told her I would pay for her to move out here with me and pay for her kids," he added. "I don't think Josh will see that this is a big deal and be truly broken till that happens."

But he revealed, his sister does not seem convinced and their parents were apparently urging her to stay with Josh.

"She said she's staying where she's at," Josh Duggar's brother-in-law pointed out about sister Anna Duggar as quoted by Cosmopolitan. "But I won't stop trying to get that pig out of our family."

He even got into an argument with other commenters who do not share his view. Others though gave him support for finally speaking up on the issue and thinking of his sister's welfare.

It was only last week when Josh admitted to cheating after the Ashley Madison hack surfaced.

"I have been the biggest hypocrite ever," he explained in a statement as quoted by CNN. "While espousing faith and family values, I have secretly over the last several years been viewing pornography on the internet and this became a secret addiction and I became unfaithful to my wife." 

Josh Duggar's brother-in-law was not the only one trying to convince Anna Duggar to leave her husband. Following the break of the new scandal, E! Online reported that netizens were clamoring as well for her to move on. Anna has yet to address the latest scandal but after the molestation scandal that Josh's got involved in earlier this year, she chose then to stay by his side.
