The impeachment of Donald Trump has set a “toxic” precedent, the Senate majority leader has said.
Mitch McConnell, the top Senate Republican, said the impeachment in the House of Representatives of the US president was “unfair”.
He said Nancy Pelosi, speaker of the House, had “failed the country” and sought to reassure the president and his supporters that “moments like this are why the United States Senate exists.”
Mr McConnell “if the Senate blesses the historically low bar, we invite the impeachment of every future president”.
Last night, the House, which is controlled by the Democrats, voted to impeach on both charges of abuse of power and obstruction of Congress after hours of debate.
This meant that Donald Trump has become the third US president to be impeached.
In an unusual move for an unusual moment in US politics, after Ms Pelosi refused to say when or whether she would send the articles of impeachment to the Senate for trial.
She said there needed to be clearer picture of how the Senate would conduct proceedings and that Senate Majority Leader Mitch McConnell and Minority Leader Chuck Schumer were negotiating over the conduct of the trial.
Her Senate rival Mr McConnell has now accused Ms Pelosi of being afraid to send “their shoddy work product to the Senate”.
On Tuesday, Mr McConnell rejected a proposal from his Democrat colleague Minority Leader Chuck Schumer to call several witnesses.
Mr McConnell also said that he is coordinating with the White House and said “I am not an impartial juror.”
