Six House Democrats are calling on FBI Director Christopher Wray to investigate whether President Donald Trump's son-in-law and senior White House aide Jared Kushner leaked classified information to Saudi Crown Prince Mohammad bin Salman, according to a letter obtained by CNN.

The call comes after The Intercept, citing three sources, reported that the Saudi prince -- known casually by his initials, MBS -- told confidantes after their meeting last year that Kushner had discussed Saudi leaders who are disloyal to the crown prince.

"We request the FBI open an immediate investigation to determine if these reports are accurate and to explore the extent to which information and sources may have been comprised," reads the letter from Democratic Reps. Ted Lieu, Gerald Connolly, Donald Beyer, Pramila Jayapal, Peter Welch and Ruben Gallego.

The letter notes that the "integrity of classified information" falls within the purview of the FBI but that "while the President has the authority to declassify and share information, the President's advisers do not."

According to The Intercept, one person "who talks frequently to confidants of the Saudi and Emirati rulers" told the publication that MBS bragged to United Arab Emirates Crown Prince Mohammed bin Zayed that Kushner was "in his pocket." The publication added that the information on the Saudi royals not loyal to him was contained within the President's Daily Brief, a document presented to the President every day that Kushner lost access to earlier this year when near security clearance rules were instituted by chief of staff John Kelly.

Kushner, in an effort to deepen that bond, took an unannounced trip to Saudi Arabia in October, where he met directly with the crown prince.

Donald Trump promised that his State of the Union address would focus on “unification.” But Trump advocating national unity is like a pyromaniac promoting lighter fluids. His goal is, and has always been, disunion.

The man thrives on divisiveness. It’s how he keeps himself the center of attention, fuels his base, and ensures that no matter what facts are revealed about him, his followers will stick by him.

There’s another reason Trump has aimed to divide — and why he continuously pours salt into the nation’s deepest wounds over ethnicity, immigration, race and gender.

Over the past four decades, while the median wage has barely budged, the incomes of the richest 0.1 of a percent have increased by more than 300 percent, and the incomes of the top 0.001 of a percent (the 2,300 richest Americans) have soared by more than 600 percent. The net worth of the wealthiest 0.1 of a percent of Americans now almost equals that of the bottom 90 percent combined.

This grotesque imbalance is undermining American democracy.

“The preferences of the average American appear to have only a minuscule, near-zero, statistically nonsignificant impact upon public policy,” Princeton’s Martin Gilens and Northwestern University’s Benjamin Page concluded a few years ago after analyzing in detail 1,799 policy issues that came before Congress. Lawmakers respond instead to the demands of wealthy individuals and moneyed business interests.

No secret there. In fact, Trump campaigned as a populist, exploiting the public’s justifiable sense that the game is rigged against them.

But he never attacked the American oligarchy, and his divide-and-conquer strategy as president has disguised his efforts to make the oligarchy even stronger.

His tax cuts, his evisceration of labor laws, his filling of Cabinet and sub-Cabinet positions with corporate shills, and his rollbacks of health, safety, environmental and financial regulations: All have made the superrich far richer, at the expense of average Americans.

Meanwhile, he and his fellow Republicans continue to suppress votes.

In recent weeks, Sens. Elizabeth Warren and Bernie Sanders, both eyeing presidential bids, have along with 29-year-old freshman Rep. Alexandria Ocasio-Cortez called for sharp increases in taxes on the superrich.

Some Democratic presidential hopefuls are also proposing to expand access to health insurance by creating Medicare for all.

Polls show strong public support, but the corporate Democrats who still bankroll much of the party are not happy with this drift to the putative “left.”

Trump, along with the Republicans and perhaps some corporate Democrats, would rather opponents focus on the same ethnic, racial and gender differences he uses to divide and conquer.

But Democratic leaders and candidates appear to understand that the largest threat to the state of the union — one that trumps all others, rendering it all but impossible to address anything else — is the deepening divide of wealth and power between the many and the few.
