MSNBC on Wednesday announced the reshuffling of its programming leadership amid complaints from NBC News chief Andy Lack over a ratings drop since the Mueller investigation wrapped up, according to Mediaite.

Senior Vice President of Programming and Development Johnathan Wald will join MSNBC Executive Editor Dan Arnall to lead daytime production, replacing NBC News Senior Vice President Janelle Rodriguez in that role, the report said.

Rodríguez will still oversee all news-gathering and editorial for dayside, along with business, tech and health units and NBC News Now — the network’s streaming service, a source told The Post.

NBC News Senior Vice President Janelle Rodriguez is departing dayside to helm NBC News Now, the network’s streaming service, the site reported.

The changes were announced at a 9 a.m. company meeting.

The TV network will also revert back to its former programming structure, a source told Mediaite — with Wald overseeing the 9 a.m.-to-noon block, while Arnall leads the noon-to-4 p.m. operations.

The network has seen its ratings slide since the Mueller investigation concluded in late March.

Their May ratings for the targeted 25-to-54-year-old demographic was down 32% year over year.
