Top Donald Trump advisor and former mayor of New York City, Rudy Giuliani, may be behind a controversial tweet directed at a NATO ally.

Pulitzer-prize winning journalist Maggie Haberman of The New York Times, reported that Giuliani may have successfully lobbied President Trump to intervene against Turkey on behalf of American Pastor Andrew Brunson.

"This is something Giuliani and his partner, as well as another lobbyist, have pushed repeatedly for Trump to address," Haberman tweeted Wednesday. "[Reince] Priebus repeatedly blocked it, per two people close to White House."

"No one has this time, she added.

Zarrab is a client of Giuliani, who was once a U.S. Attorney.

In 2017, Giuliani reportedly traveled to Turkey to meet with Turkish president Recep Tayyip Erdogan on behalf of Zarrab.

This is not the only time Giuliani's name has surfaced in connection to a scandal involving Turkey.

Turkish-Iranian gold trader Reza Zarrab is linked to both Giuliani and former National Security Advisor Michael Flynn.

Special counsel Robert Mueller is reportedly investigating whether Zarrab and Flynn conspired to "whisk away" a Muslim cleric in a "dead of night" kidnapping.
