Ex-Breitbart spokesman outlines why Trump's tax returns — and not Russia — are his 'greatest vulnerability'

A former Breitbart spokesman and GOP operative advised Democrats to go after Donald Trump's taxes — and not Russia — if they want to take him down.

"Cheating on your taxes may not seem sexy, but this scandal may very well represent Trump’s greatest vulnerability should Democrats retake control of Congress in November," political commentator Kurt Bardella wrote in an NBC News column published Wednesday.

The New York Times' bombshell report on the various tax fraud schemes employed by the president's father Fred Trump, Bardella wrote, got "buried" beneath the circus surrounding Brett Kavanaugh's confirmation to the Supreme Court.

In the wake of the report, however, oversight committee chairpersons can and should utilize "the power to issue subpoenas for Trump’s tax returns and the financial records of the Trump business empire," the ex-GOP operative wrote.

"Remember, this is an empire that continues to do business with the federal government, further enriching the Trump family despite grave concerns about conflicts on interest in the executive branch," Bardella wrote. "Not surprisingly, so far, these conflicts have gone mostly unchecked by Republicans in Congress."

The former spokesperson for the House Oversight & Government Reform Committee noted that although candidate Trump promised "absolutely" to release his tax returns during an interview with MSNBC's Chuck Todd, he never did — and the Times' report detailing decades of tax fraud and evasion "sheds light on the real reason why."

"Trump’s entire identity is rooted in the myth he has repeated so frequently he may very well believe it, 'I built what I build myself,'" Bardella noted. "The unraveling of that lie could even lead to the beginning of the end for Trump and his presidency."
