A former aide to President Donald Trump used to make trips to a McDonald’s restaurant near the White House to satisfy the president’s burger cravings, according to Politico.

The website reported the detail in a profile of former aide Keith Schiller, who was scheduled to appear Tuesday before the House Intelligence Committee to testify as part of the panel’s Russia investigation.

Schiller, a Trump Tower security guard turned White House aide, left the administration in September but was expected to be asked about Trump’s 2013 trip to Russia, according to Politico.
