WASHINGTON (VINnews) — President Donald Trump cut short a television interview after a heated exchange with NBC moderator Kristen Welker over his allegations of election irregularities.

The interview became increasingly contentious when Welker pressed Trump to provide evidence supporting his claims about election problems in California. Trump defended his position, while Welker challenged the basis for those assertions.

As the discussion continued, Trump criticized several major news organizations, accusing them of unfair and biased coverage. He then indicated that he no longer wished to continue the interview and brought the conversation to an end.

Welker attempted to continue asking questions as Trump prepared to leave, but the president declined to remain for further discussion.

The White House did not immediately issue a statement regarding the exchange.

The interview also touched on a range of domestic and foreign policy issues, including the economy and tensions involving Iran.

The confrontation was the latest in a series of public disputes between Trump and members of the news media. Throughout his political career, Trump has frequently accused major news organizations of bias, while journalists have continued to challenge him on a variety of policy positions and factual claims.

Video clips of the exchange circulated widely online following the broadcast, drawing reactions from both supporters and critics of the president.
