With an ongoing global pandemic and a national election five months away, many state election officials are looking to expand mail-in voting as an alternative to waiting in line at polling locations. As co-chair of the new bipartisan group called VoteSafe, Tom Ridge, a former Republican governor and the nation's first Secretary of Homeland Security, is advocating for safe in-person voting and the expansion of voting by mail. This week, President Donald Trump and Attorney General William Barr made unverified claims that foreign actors could tamper with mail-in ballots. Ridge tells CBS News' political correspondent Caitlin Huey-Burns why the president's claims are simply false and why Trump should be encouraging absentee ballots if he wants to win re-election. Ridge says he's confident in this November's election, despite efforts of foreign interference.
