HAMBURG, Germany - Donald Trump and Vladimir Putin agree on one aspect of Moscow's meddling in the 2016 U.S. presidential campaign: The issue has become a hindrance to better relations.
 
That's according to Secretary of State Rex Tillerson, who says the U.S. and Russian presidents had a "robust and lengthy" discussion about the interference, though Putin denied involvement.
 
Tillerson's Russian counterpart, Foreign Minister Sergey Lavrov, says Trump accepted Putin's assurances that Russia didn't meddle in the U.S. election.
 
U.S. lawmakers of both parties had demanded that Trump not shy away from the issue in his highly anticipated meeting with Putin. Trump has avoided stating unequivocally in the past that Russia interfered, even as investigations proceed into whether his campaign colluded with Russians who sought to help him win.
