MOSCOW (Reuters) - Russian Foreign Minister Sergei Lavrov said on Wednesday he wanted to be shown at least one fact proving Moscow’s meddling in the 2016 U.S. presidential election.

“I don’t know anything about this fact. It’s amazing that serious people are making a mountain out of a molehill,” Lavrov told a news conference during a visit to Belgium. His comments were broadcast live by Russian state Rossiya 24 TV channel.

Lavrov was reacting to reports that U.S. President Donald Trump’s eldest son was blamed for meeting a Russian lawyer that emails show might have had damaging information about Hillary Clinton last year.
