Trump's senior Homeland Security adviser once claimed Obama's CIA director was a secret Muslim

Frank Wuco, a White House senior adviser to the Department of Homeland Security, used to be a conservative radio host who promoted right-wing conspiracies meant to discredit officials in the Obama administration.

As CNN's KFile team reports, Frank Wuco, who has worked for the White House and Homeland Security since January, pushed a number of "unfounded" conspiracy theories. Those theories include "claims that former President Barack Obama's memoir was ghost written by former anti-Vietnam War radical Bill Ayers, claims that former CIA director John Brennan converted to Islam and claims Attorney General Eric Holder had been a member of the Black Panthers."

Earlier in December, KFile also reported that Wuco (like Trump) pushed "birtherism" -- a theory that claimed Obama was not born in the U.S. and had faked his birth certificate to be eligible for the presidency.

Wuco's apparent obsession with Obama's past led him to publish a book (later turned into a film) titled "Dreams from My Real Father," a take on the former president's book "Dreams from My Father." In his book, Wuco claimed Obama's actual father "was a family friend named Frank Marshall Davis."

When Hillary Clinton was still secretary of state, Wuco claimed that the parents of her aide and confidante Huma Abedin were members of the Muslim Brotherhood -- claims that were dispelled as demonstrably false by The Washington Post and PolitiFact. The report notes that even Sen. John McCain (R-AZ) decried the false allegations, calling them an "unwarranted and unfounded attack on an honorable woman, a dedicated American and a loyal public servant."

When KFile published their initial report on Wuco's birtherism, DHS said his views have "no bearing on his ability to perform his job for the American people," and were "years-old comments cherry-picked from thousands of hours" of audio.
