In a significant move, the Biden campaign held a press conference outside the courthouse doors on Tuesday, displaying their increased involvement in Donald Trump's criminal trial. This development injected the president's key campaign themes into the media coverage, but also provided ammunition for Trump's team, who claim that the prosecution is politically motivated.

Up until now, both the White House and the president's reelection campaign have diligently avoided addressing Trump's four separate criminal cases. The intent was to safeguard the independence of federal and local prosecutors against Trump's baseless accusations. The claims made by Trump without any evidence suggested that the charges were orchestrated and fabricated to damage his candidacy.

As the Manhattan district attorney's office presents closing arguments on charges related to falsifying business records to conceal hush money payments to an adult-film actress ahead of the 2016 election, Tuesday's press conference indicates the Biden campaign's willingness to engage with Trump's trial. The move aims to address the core campaign issues raised by the president, but it also feeds into the narrative of the prosecution being politically driven.

The Trump campaign immediately seized upon this development, characterizing it as an acknowledgement that the trial is politically motivated and a sign of the Biden campaign's struggles. They argue that the active involvement of the Biden team only reinforces their claim that the charges against Trump are part of a broader effort to undermine his candidacy.

As the trial gains momentum, it remains to be seen how the increased engagement of the Biden campaign will impact the public's perception of the proceedings. With Trump's attorneys and the Manhattan district attorney presenting their closing arguments, the outcome of this trial will undoubtedly have implications for both Trump's political future and the credibility of the prosecution.

The Biden campaign's decision to step into the spotlight of Trump's trial suggests a strategic calculation, as they attempt to address and counter the president's campaign themes head-on. However, it also opens the door for the Trump camp to further argue that the trial is tainted by political motives.

With the trial still ongoing, the focus must shift to the evidence and arguments presented, allowing the justice system to play out independently and determine the outcome. Only time will tell how this high-stakes trial will ultimately impact the upcoming 2020 presidential election.
