Castro, a member of the House Intelligence Committee, responded to a question from MSNBC's Joy Reid on whether he believed the information he had seen so far in the committee's investigation of Russia's election interference was evidence of a crime.

"Do you believe that you heard evidence of crimes committed by members of this administration?" Reid asked.

"Yes," Castro responded.

He added that he believed Republicans were not giving the House and Senate investigations enough resources to properly track down leads and make recommendations to avoid future election interference by Moscow.

"A big concern that I have is that there's not enough resources, or energy or time that's been committed to tracking down the leads that have been given to us," Castro said.
