President Donald Trump is blasting ‘‘totally biased and fake news reports of the so-called Russia story.’’

Trump took to Twitter Thursday to express his frustration. He singled out reports on NBC and ABC, saying ‘‘such dishonesty!’’

The FBI director said earlier this week that there is an investigation underway into whether Trump’s campaign associates coordinated with Russian officials in an effort to sway the 2016 presidential election. The president has refused to acknowledge the probe, dismissed it as fake news and blamed it on Democrats.

Rep. Adam Schiff, the ranking Democrat on the House intelligence committee, said Wednesday that he had seen ‘‘more than circumstantial evidence’’ that Trump associates colluded with Russia.
