US Supreme Court rejects Republican bid to stop Biden's Pennsylvania win

The US Supreme Court has denied the Republicans' last bid to change President-elect Joe Biden's victory in Pennsylvania. But Republican senators say even now that this is not over yet.

Donald Trump and his legal teams have been fighting official results from the November 3 election, but the legal hurdles have regularly been thrown out of state courts. Meanwhile, the outgoing president has continued to repeat claims of public fraud, evidence-free.

This time even the nation's highest court with its traditional majority was unimpressed.

The Supreme Court, without comment, refused to call into question the certification process in Pennsylvania on Tuesday. Democratic governor, Tom Wolf, has already certified Biden's 80,000-strong victory over Trump.

The state's 20 electors are to meet on 14 December to cast their votes for Biden.

The state's high court said the plaintiffs waited too long to file the challenge and noted the Republicans' huge demand that an entire election is overturned retroactively.

Republicans had pleaded with the authorities to intervene immediately after the state Supreme Court turned away their case last week.

The Republicans argue that Pennsylvania's open vote-by-mail law is unconstitutional because it required a representative amendment to authorise its provisions. Just one Republican state legislator voted against its section last year in Pennsylvania's Republican-controlled Legislature.

"Even Trump nominees & Republicans saw this for what it was: a charade," Lamb said on Twitter.
