Turkish President Recep Tayyip Erdogan 'sometimes phoned White House at least twice a week and was put through directly to President,' CNN reported referring to sources.

According to sources, President Trump's phone calls alarmed US officials.

"By far the greatest number of Trump's telephone discussions with an individual head of state were with Erdogan, who sometimes phoned the White House at least twice a week and was put through directly to the President on standing orders from Trump, according to the sources. Meanwhile, the President regularly bullied and demeaned the leaders of America's principal allies, especially two women: telling Prime Minister Theresa May of the United Kingdom she was weak and lacked courage; and telling German Chancellor Angela Merkel that she was "stupid," the edition noted.  

Sometimes Erdogan reportedly reached Trump on the golf course and he 'would delay play while the two spoke at length.'
