Sen. Lankford was “caught off guard” by news of Trump-Putin congratulatory call

The Senate Intelligence Committee is holding a hearing about the ongoing threat to U.S. elections. It comes a day after the committee released its first report into Russian interference in the 2016 election, which suggests states need more resources. Oklahoma Republican Sen. James Lankford, a member of the Senate Intelligence Committee, joins “CBS This Morning” to discuss the hearing and President Trump’s congratulatory call to Russian President Vladimir Putin.
