Here's what Jim Cramer had to say about some of the stocks during the Mad Money Lightning Round:

Chesapeake Energy (CHK) : "They are cleaning up the balance sheet. I say buy, buy, buy."

Inovio Pharmaceutical (INO) : "I don't like the vaccine business or being in the crosshairs of the President."

SeaWorld Entertainment (SEAS) : "I would go with Comcast (CMCSA) and not SeaWorld."

Northern Trust Corp (NTRS) : "I prefer Citigroup (C) and even Wells Fargo (WFC) ."

Cramer says investors really should buy the stocks Trump slams on Twitter.
