A group of Republican Senators is demanding that a special counsel be tasked with investigating Hunter Biden.

In a statement, Senator John Cornyn of Texas says there's mounting evidence that President Biden's son committed numerous federal crimes including tax fraud, money laundering and foreign-lobbying violations.

The senators say the special prosecutor is needed to avoid the appearance of political influence.
