Media Matters today reports [emphasis added]:

After having criticized other media for inadequately covering the June 1 shooting at an Army recruiting center in Arkansas, which resulted in the death of Pvt. William Long, Fox News host Sean Hannity has devoted a total of one sentence over two editions of his Fox News show to the June 10 shooting of Stephen T. Johns, a security guard at the Holocaust Memorial Museum in Washington, allegedly by white supremacist James W. von Brunn.

Nope, nothing to see here folks, just keep moving along.
