Billionaire Tom Steyer says he's thankful that law enforcement officials recovered a second package addressed to him that appears similar to those containing pipe bombs that were sent to prominent Democrats.

The wave of pipe bombs addressed to prominent Democrats has raised fresh questions about the ability of the U.S. Postal Service and private delivery companies to intercept explosives and other dangerous items.
