Something’s fishy about this.

Homeland Security Secretary Alejandro Mayorkas spent less than six hours visiting hurricane-hit areas of North Carolina on Thursday — before retreating to Washington to grab an early takeout dinner at Nobu.

Mayorkas touched down in the Tar Heel State around 10 a.m. before jetting back to the nation’s capital, where he was spotted by The Post at 5:15 p.m. carrying bags of food from the posh international Japanese restaurant chain — where sushi and sashimi selections are priced at $60 a plate and the highest-grade Wagyu steaks go for $40 per ounce.

A photographer snapped the apparently peckish Mayorkas, 64 — still wearing his navy blue suit and white dress shirt — exiting the Northwest DC establishment at 5:30 p.m., just 30 minutes after it opened.

The cabinet official was home by 5:40 p.m., dodging DC’s notorious rush-hour traffic.
