Top Senate Republican Mitch McConnell has denounced US President Joe Biden’s voting rights speech as “incoherent” and “profoundly unpresidential”.
The remarks come one day after Mr Biden delivered a fiery speech in Atlanta calling for an overhaul of the US election system.
The president said he supported changes that would allow his party’s proposed overhaul of the election system to be passed without the support of opposition Republicans.
Currently, a majority of 60% is needed to pass most legislation in the Senate.
