President Donald Trump said on Wednesday that former FBI Director James Comey's Senate testimony is "loaded up with lies." Jonathan Ernst/Reuters President Donald Trump will sometimes "tune out" his top national security adviser, Axios reported on Friday.

When National Security Adviser H. R. McMaster gives Trump daily national security briefings, he likes to stick to his points, sources who have worked with him told Axios.

Trump, however, often "likes to be discursive and will frequently turn to others or meander into other subjects."

"Can you believe this guy" Trump reportedly joked of McMaster.

When McMaster starts delving into points regarding national security, Trump "sometimes simply tunes McMaster out," Axios reported.

In the past, other advisers have also revealed that Trump likes to keep his daily security briefings short and full of "killer graphics."

Sources told Axios that, to adjust, McMaster has been keeping his briefings shorter and using more conversational language in order to keep Trump engaged.
