One of the most experienced prosecutors the United States Senate explained the legal importance of Friday's filings during an appearance on MSNBC's "Hardball" with Chris Matthews.
Sen. Richard Blumenthal (D-CT) was the United States Attorney for Connecticut during the Carter administration and was elected five times as Attorney General in the state -- serving for 20 years. He is now a member of the Senate Judiciary Committee.
"How do you react to the Southern District of New York's report that the president directed the criminal violation of the campaign laws to cover up his affairs with Susan McDougal and with Stormy Daniels?" Matthews asked.
"This sentencing memorandum, first of all, is a bombshell in showing why prosecutors in the Southern District of New York -- independent of the special counsel -- believe that Donald Trump committed a felony that enabled him or at least helped him to become president," Blumenthal replied.
"And covering up those payments was part of what was done, part of the conspiracy in which Donald Trump is an unindicted co-conspirator," he continued. "Think of it for a moment, unindicted co-conspirator."
"And the further information in this bombshell memorandum shows facts and evidence that link that conspiracy to Russian collusion with the Trump campaign and potentially obstruction of justice," Blumenthal noted.
"So the pieces of the mosaic or the puzzle are coming into place, and the walls are closing in on Donald Trump and his inner circle, including his family," he added.
Blumenthal predicted that "as the walls close in on Donald Trump, he is going to be more desperate, more destructive, and potentially more damaging."
