AUSTIN, Texas -- The chairman of the U.S. House Homeland Security committee said he thinks the latest package explosion in Texas will lead to more evidence, “hopefully fingerprints and surveillance photos.”

Rep. Michael McCaul, a Republican from Texas, made the comments Tuesday at a White House roundtable discussion on so-called sanctuary cities. It's not clear whether McCaul was speaking with knowledge of specific information in the case.

McCaul, whose district includes Austin, says he hopes the bomber's "biggest mistake was going through FedEx."

He also thanked President Donald Trump for sending 500 federal agents to Austin “to find this perpetrator and bring him to justice.”

A package exploded early Tuesday at a FedEx distribution center near San Antonio. Texas Attorney General Ken Paxton says the package was sent from Austin and was addressed to a home in Austin.

Four other package bombs have exploded in Austin since March 2.
