Trump on Friday sought to exploit potential frustration among Democrats, accusing party leaders of deliberately diminishing Sanders's chances of winning the nomination by keeping him off the campaign trail.

"They are rigging the election again against Bernie Sanders, just like last time, only even more obviously," Trump tweeted. "They are bringing him out of so important Iowa in order that, as a Senator, he sit through the Impeachment Hoax Trial."

Sanders this week said he was concerned about losing time on the campaign trail during the weeks-long trial.

“I would rather be in Iowa today. There’s a caucus there in 2 1/2 weeks. I’d rather be in New Hampshire and Nevada and so forth. But I swore a constitutional oath as a United States senator to do my job and I’m here to do my job,” he said Thursday.
