Washington CNN  — 

President Donald Trump on Monday accused the Obama administration of using the investigation into potential ties between his campaign and Russia’s meddling in the 2016 election to discredit his bid and boost the chances of his Democratic opponent, Hillary Clinton.

“Why did the Obama Administration start an investigation into the Trump Campaign (with zero proof of wrongdoing) long before the Election in November? Wanted to discredit so Crooked H would win. Unprecedented. Bigger than Watergate! Plus, Obama did NOTHING about Russian meddling,” Trump tweeted Monday morning.
