TEHRAN, Young Journalists Club(YJC)_The senators voted 51 to 49, almost across party lines, against the proposal on Friday.
The vote stopped Democrats' drive to hear testimony from witnesses like former national security adviser John Bolton.
The senate should now vote to convict or clear Trump of the impeachment charges.
After the Friday vote, Senate Republican leader Mitch McConnell said he aims to conclude the trial in the coming days.
He postponed the final vote on articles of impeachment until Wednesday in the face of opposition from Senate Republican moderates to his plan to wrap up the trial Friday or Saturday without deliberations.
For Senate Republicans to not allow witnesses or documents in an impeachment trial, it is a cover-up.

They didn't live up to their responsibilities to the country.

Senate Minority Leader Chuck Schumer criticized the Republicans’ move as a great cover-up.
"America will remember this day, unfortunately, where the Senate did not live up to its responsibilities, where the Senate turned away from truth and went along with a sham trial," Schumer told reporters.
