Mayor de Blasio on Monday dismissed complaints that his legal team stymied a Department of Investigation probe into a shady land deal that was approved by his administration last year.

Asked about a DOI report that highlighted a lack of cooperation by the city’s Law Department, Hizzoner did little more than shrug.

“I think it’s totally normal — two different institutions with two different jobs to do,” he said about the probe into the Rivington House nursing-home deal. “I’m sure they’ll work that out.”
