President Donald Trump has made his first public comments on the Austin bombings that have rocked the city. On this edition of Capital Tonight, we told why one local congressman says a blast at a FedEx facility could lead to a suspect.

Also, Professor Randall Rogan played a key role in helping identify the "unabomber." He joined us to discuss the technique of trying to get the perpetrator to make contact with police. 

Plus, a former FBI agent discussed the process behind the ongoing investigation.
