President Donald Trump and Sen. David McCormick of Pennsylvania are touting tens of billions of dollars of energy and tech investments at a new summit focusing on energy and innovation. "This is a really triumphant day for the people of the commonwealth and the United States of America," Trump said Tuesday as he took the stage at the summit. Pennsylvania is a swing state critical to Trump's wins in 2016 and 2024, and is at the forefront of his energy agenda. On a panel discussion, Commerce Secretary Howard Lutnick said the Trump administration won't let the U.S. lose the artificial intelligence race. Participating companies at the conference include Blackstone, Bridgewater, SoftBank, Amazon Web Services and ExxonMobil.

President Joe Biden is making a rare jump into the 2024 battleground political fray since ending his reelection bid. He'll campaign on Tuesday in Pennsylvania for a close ally and visit Wisconsin to spotlight a signature legislative achievement. But as Biden makes a quick swing through the key states, two Democratic senators locked in competitive reelection battles are taking markedly different approaches to the outgoing president. Biden was fully embraced by Sen. Bob Casey when he participated in an evening campaign fundraiser in Philadelphia with Pennsylvania's senior senator. But in Milwaukee, where Biden spotlighted his administration's efforts to replace the nation's toxic lead pipes, incumbent Democratic Sen. Tammy Baldwin was conspicuously absent.
