The report revealed that Mr Paxton, who is said to have filed the Texas lawsuit, hired Lawrence Joseph as a special outside counsel through an “unusual contract” on 7 December.
Mr Joseph had earlier intervened in a US court to support Mr Trump’s efforts to block the release of his income-tax returns.
“The same day [7 Dec] the contract was signed, Mr Paxton filed his complaint with the Supreme Court. Mr Joseph was listed as a special counsel, but the brief did not disclose that it had been written by outside parties,” said the report.
Mr Paxton, however, was not the first choice for Trump’s team to overturn Joe Biden’s victory in swing states as he had criminal investigations going on against him.
