Democrat's spending plans have once again been thrown a wrench by Sen. Joe Manchin.

According to The Washington Post, the lawmaker told the Democrats that he wouldn't support an economic agenda that included climate change spending or tax increases.

The roadblock comes just as Democrats began reviving parts of their economic agenda with Manchin's apparent support after the moderate Democrat tanked the original $2 trillion build back better act at the end of last year.

Democrats have been trying to get Manchin's support back in order to pass Biden's economic agenda before the elections. Several agreements between the moderate and his party are at risk of being upended by Manchin's refusal to budge on climate spending

According to The Post, Manchin said he was open to the Democrats' proposal to cut prescription drug prices. The reconciliation process allows Democrats to pass the measure using a simple majority vote.

A spokesman for Manchin didn't reply to Insider's request for comment.
