WASHINGTON (Reuters) - President Donald Trump's longtime adviser Roger Stone was convicted on all charges on Friday by a federal court jury that found the veteran Republican operative and self-proclaimed "dirty trickster" guilty on seven counts of lying to the U.S. Congress, obstruction and witness tampering.

During the trial, prosecutors pressed their case that Stone lied to lawmakers about his outreach to WikiLeaks - the website that disclosed many hacked Democratic emails ahead of the 2016 U.S. election that proved embarrassing to Trump's Democratic opponent Hillary Clinton - to protect Trump from looking bad.
