Minn., confronted Republican Sen. Mike Lee of Utah on Capitol Hill Monday after he posted unfounded claims on social media that the alleged gunman who shot two legislators and their spouses is a liberal and may have been associated with Gov.

Sen. Amy Klobuchar D-Minn., said she also planned to confront Lee. “There was no Father’s Day for [Hortman’s] children,” she said on MSNBC’s Morning Joe. “This is not a laughing matter, and certainly what we are seeing in increasing violence and this evil man who did this, this is not a joke.”
