Mitch McConnell, the US Senate's longest-serving Republican leader, has announced his retirement from leadership after the upcoming November elections.

His decision to step down has been influenced by pressure from hard-right senators and his stance on securing aid for Ukraine.

McConnell's leadership tenure is viewed critically for missed opportunities and not improving the Senate.

His most notable moment, the impeachment trial speech against Trump, ended without a conviction, leaving a blemish on his legacy.

Potential successors for McConnell's role include John Barrasso, John Cornyn, and John Thune, with the selection process expected to be impacted by Trump's influence.

The Supreme Court is set to rule on Trump's claim of presidential immunity regarding criminal election interference charges.

Hunter Biden has contested Republican allegations about his business activities and his father's involvement during his congressional testimony.
