Blue Bloods is airing a new episode tomorrow night called "Poetic Justice". Here is the plot summary:

Also, Frank and Mayor Chase (Dylan Walsh) butt heads over an off-duty cop who goes too far making a political statement; Anthony worries Erin’s DA campaign could be threatened by her ex-husband Jack’s unsavory business connections; and Jamie investigates a potentially dirty officer whose identity may be close to home.
Here are a couple preview clips:
