Authorities have arrested Cody Balmer, 38, for setting fire to Pennsylvania Governor Josh Shapiro's mansion. Fellow potential 2028 presidential candidates, including J.B. Pritzker, Gretchen Whitmer, and Gavin Newsom, expressed support for Shapiro. The National Governors Association also condemned the attack. The incident comes amid a rise in political violence in the US, with a recent study revealing an increase in attacks on political figures and institutions. Shapiro called for an end to such violence and emphasized the need for society to be better.
