(CNN)Sen. Bernie Sanders on Sunday said it's urgent that Democrats work toward an infrastructure package with a larger price tag that addresses climate change and other related issues.

"I sometimes think we get boggled down in numbers and that's important, but we've got to look at what the needs are of the American people, what's going on right now," Sanders, a Vermont independent senator who caucuses with the Democrats and chairman of the Senate Budget Committee, told CNN's Dana Bash on "State of the Union."

The comments from Sanders come as Democrats eye a bipartisan track and budget reconciliation track in negotiations over President Joe Biden's bipartisan infrastructure proposal.

Asked if he had Biden's blessing to push a separate $6 trillion reconciliation plan, Sanders said the President provided a "serious and comprehensive blueprint."
