“This is a BFD,” Obama tweeted Tuesday, quoting his former vice president’s tweet about signing the deflation law. Obama referenced a moment in 2010 when Biden was caught on a hot mic telling Obama that signing the Affordable Care Act, often referred to as ObamaCare, was a “big deal.” At an event focused on the Affordable Care Act earlier this year, Biden jokingly mentioned the hot mic moment to Obama as he left the podium to sign an executive order. “Now, I’m going to sign an executive order and, Barack, let me remind you: It’s a hot microphone,” Biden told Obama. In response to Obama’s tweet, Biden simply replied, “Thanks, Obama.” Trump-backed candidate wins Wyoming secretary of state nomination Watch live: Cheney concedes Wyoming primary loss to Hageman Biden signed the Inflation Reduction Act on Tuesday. The sweeping $740 billion package will lower health care costs, address climate change, reform the tax code and provide funding to the IRS to expand enforcement. Biden added that the recently signed legislation will help people’s lives improve. “With unwavering conviction, commitment and patience, comes progress,” Biden said during the bill’s signing. “And when it does, as it does today, people’s lives improve and the future becomes brighter and a nation can be transformed.”
