Watch Live: Republican Senator Tim Scott delivers response to President Biden's address

Republican Senator Tim Scott is delivering a speech responding to President Joe Biden's first address before a joint session of Congress on Wednesday evening. The response provides an opportunity for Scott, a rising star in the Republican Party, to outline an alternative to the president's ambitious legislative agenda.

Scott is delivering his response after Mr. Biden concludes his speech, which was expected to include details about his American Families Plan, a tax and spending bill focused on health care, child care and education. Between this and the American Jobs Plan, his infrastructure proposal, Mr. Biden is calling on Congress to pass over $4 trillion in spending on major projects. Republicans have balked at the price tags for these proposals, questioned their relevancy, and criticized Mr. Biden's plan to raise certain taxes to pay for them.
