US President Joe Biden has called for a historic change to Senate rules as he seeks to overhaul the country’s election laws.
In an impassioned speech, he said he supported changes that would allow his voting reforms to be passed without the support of opposition Republicans.
Misgivings from two senators in his party are hampering his plans, and no Republicans have backed them.
Currently, a majority of 60% is needed to pass most legislation in the Senate.
And with the upper chamber of Congress split 50-50 between the two parties, Mr Biden’s sweeping election bills are almost certain not to pass unless there is a change to that rule.
