Attorney General Jeff Sessions Jefferson (Jeff) Beauregard SessionsGOP set to release controversial Biden report Trump's policies on refugees are as simple as ABCs Ocasio-Cortez, Velázquez call for convention to decide Puerto Rico status MORE argued in 1999 as an Alabama senator that then-President Clinton could be removed from office for obstructing justice amid an investigation into his relationship with White House intern Monica Lewinsky.

The Justice Department head's argument during the Clinton impeachment trial more than two decades ago contradicts the claim of President Trump's personal lawyer that the president cannot legally obstruct justice.

“The chief law officer of the land, whose oath of office calls on him to preserve, protect and defend the Constitution, crossed the line and failed to defend the law, and, in fact, attacked the law and the rights of a fellow citizen,” Sessions said during Clinton’s trial in the Senate, according to his remarks archived in the congressional record.

“Under our Constitution, equal justice requires that he forfeit his office,” the Alabama senator continued.

Politico first reported Sessions's impassioned case on Monday.

The "president cannot obstruct justice because he is the chief law enforcement officer under [the Constitution's Article II] and has every right to express his view of any case," Trump attorney John Dowd told Axios.

Dowd also claimed that he mistakenly crafted a tweet sent from the president's twitter account over the weekend that appeared to suggest the president knew in January that Michael Flynn, his former national security adviser, had lied to the FBI as well as Vice President Pence.

Last week, Flynn pleaded guilty to lying to federal investigators about his conversations with a top Kremlin official.

Politico also noted that 17 current senators also supported the obstruction of justice charge against Clinton, including Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellPelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Senate GOP aims to confirm Trump court pick by Oct. 29: report Trump argues full Supreme Court needed to settle potential election disputes MORE (R-Ky.), Senate Judiciary Committee Chairman Chuck Grassley Charles (Chuck) Ernest GrassleyCollins says she will vote 'no' on Supreme Court nominee before election The Hill's Morning Report - Sponsored by Facebook - Trump, GOP allies prepare for SCOTUS nomination this week Gardner signals support for taking up Supreme Court nominee this year MORE (R-Iowa) as well as Senate Intelligence Committee Chairman Richard Burr Richard Mauze BurrRep.
