The criminal trial of President Donald Trump's long-time adviser, Roger Stone, began on Tuesday with the start of jury selection as he faces charges arising from former special counsel Robert Mueller's investigation that documented Russian interference to help Trump win the 2016 U.S. election.

The trial could renew attention on efforts by Trump's 2016 campaign to capitalize on emails embarrassing to his Democratic opponent, Hillary Clinton, that U.S. intelligence officials have concluded were stolen by Russian state-backed hackers.

It also coincides with the impeachment inquiry against the Republican president in the House of Representatives over Trump's request that Ukraine investigate a Democratic rival, Joe Biden.
