During a news briefing marking the one-year anniversary of his presidency, Biden said he did not overpromise on his agenda, but did underestimate Republican opposition.

"I did not anticipate that there would be such a stalwart effort to make sure that the most important effort was to make sure President Biden didn't get anything done," he said.

Biden added: "Name me one thing they're for."
