WASHINGTON After months of haggling with President Joe Biden and other Democrats, Sen. Joe Manchin (D-W.Va.) dashed his partys hopes on Sunday by announcing he wouldnt vote for the Build Back Better legislation.

Publicly, his biggest gripes are about the cost of the bill. But privately, Manchin has told his colleagues that he essentially doesnt trust low-income people to spend government money wisely.

In recent months, Manchin has told several of his fellow Democrats that he thought parents would waste monthly child tax credit payments on drugs instead of providing for their children, according to two sources familiar with the senators comments.

Continuing the child tax credit for another year is a core part of the Build Back Better legislation that Democrats had hoped to pass by the end of the year. The policy has already cut child poverty by nearly 30%.

Manchins private comments shocked several senators, who saw it as an unfair assault on his own constituents and those struggling to raise children in poverty.

Manchin has also told colleagues he believes that Americans would fraudulently use the proposed paid sick leave policy, specifically saying people would feign being sick and go on hunting trips, a source familiar with his comments told HuffPost.

Manchins office declined to comment for this story.

In a statement on Sunday, he said he opposed the Build Back Better agenda largely because of its cost.
