WASHINGTON (Reuters) - Questions about President Donald Trump and the investigation into whether his 2016 election campaign colluded with Russia overshadowed a Senate hearing on Wednesday with U.S. Attorney General Jeff Sessions, who has been a frequent target of Trump's public attacks.

Sessions was the sole witness at the hearing on the Justice Department's proposed 2019 budget, where Democrats repeatedly drew the spotlight to the Russia probe.
