Washington: Roger Stone, a confidant of President Donald Trump, was arrested on Friday morning in the special counsel's Russia investigation and was charged with lying to Congress and obstructing the probe.

The seven-count indictment against Stone, a self-proclaimed "dirty trickster," is the first criminal case in months from special counsel Robert Mueller and provides the most detail to date about how Trump campaign associates were aware in the summer of 2016 that emails had been stolen from the Hillary Clinton campaign and wanted them released.
