Activist David Hogg took a jab at the GOP on Tuesday by saying their plan to address climate change is to send “thoughts and prayers.”

“I’m guessing thoughts and prayers,” Hogg wrote.

The Parkland survivors, many of whom are now nationally recognized as gun control advocates, have repeatedly condemned lawmakers saying they are sending “thoughts and prayers” in the wake of mass shootings.

The phrase has often been used by activists in order to make their point about the importance of gun control legislation.

In December, Hogg sarcastically offered “thoughts and prayers” to the National Rifle Association after Maria Butina, a Russian woman with ties to the group, pleaded guilty to acting as an unregistered foreign agent.
