Lawrence O'Donnell said President Donald Trump lies every time he uses the phrase “if you want to know the truth.”

O'Donnell's analysis focuses on the reliability of presidential communication regarding international conflict. The host said that identifying linguistic patterns can reveal when the administration is misleading the public about critical foreign policy outcomes.

Speaking on the MS NOW program, O'Donnell highlighted a specific seven-word phrase [1] that he believes the president employs as a marker for dishonesty. O'Donnell said the president uses this "strange" phrase when he is lying.

This pattern is particularly evident in discussions regarding a war in Iran. O'Donnell said that no one believes any of Donald Trump's deadlines for his war in Iran because Donald Trump has lied repeatedly every single time he has asked when his war will end. He said that Iran has not lied once about when the war will end.

O'Donnell said that the president has a predictable habit of using certain language to obscure facts. By honing in on these seven words [1], O'Donnell said that the public can more easily spot a lie. The host said these repeated false statements regarding the timeline of the Iran conflict significantly undermine the credibility of the U.S. government.

The analysis of these verbal cues is part of a broader effort by O'Donnell to scrutinize the transparency of the executive branch. He said that the frequency of these specific phrases correlates with a lack of factual accuracy in the president's public statements.

"He uses this 'strange' phrase when he is lying."

This critique reflects a growing trend of media analysts using linguistic forensics to challenge the veracity of political leaders. By focusing on a specific phrase, O'Donnell is attempting to provide a heuristic for the public to evaluate the credibility of presidential claims, particularly those involving high-stakes military deadlines and foreign diplomacy.
