Jack Smith wants to make his case against Donald Trump to Congress — but he's walking into a political and legal minefield. The Biden-era special counsel who brought the first and only federal criminal charges ever leveled against a former president is set to testify behind closed doors Wednesday to the House Judiciary Committee. To do so, he must navigate Byzantine secrecy laws and rules that limit what he can disclose to lawmakers. All the while, Republicans are looking to trip him up and incriminate him, to portray him as a tool of a weaponized Justice Department — an allegation they've brandished amid recent revelations that Smith obtained phone records of at least eight GOP senators as part of his probe into Trump's efforts to subvert the 2020 election results.
