Mark Levin called Pelosi a “fascist” for postponing the State of the Union, but in 2014 he urged Republicans to boycott the address 

On the January 23 edition of his radio show, Mark Levin railed against Speaker of the House Nancy Pelosi for her decision to revoke an invitation to President Donald Trump to give the customary State of the Union address so long as the government remains shut down. Levin denounced Pelosi’s decision, calling her a “fascist” multiple times and accusing her of “destroying” a “long-held tradition” because she doesn’t want Trump to give the speech with “pomp and circumstance.” But Levin hasn’t always been so committed to the integrity of the State of the Union address. In fact, when Barack Obama was president in 2014, the radio host urged Republicans to boycott the address “so half of the House floor” would be empty while Obama spoke:       

From the January 23 edition of Westwood One's The Mark Levin Show:

MARK LEVIN: [Nancy Pelosi] is literally destroying certain long-held traditions in this country. Her decision today to revoke an invitation to the president to speak before a joint House and Senate Congress -- it is the first time in American history an invitation of that sort has been withdrawn.

She does not want the president of the United States to be able to deliver the State of the Union address from the Capitol with all the pomp and circumstance. And I find it troubling that some of these conservatives and pseudo-conservatives say, “It’s no big deal, he’s destroying -- the president -- another tradition.” He’s not destroying anything, Nancy Pelosi is. They are denying a duly elected president -- who most of you voted for -- the right that every president who’s wanted to do so, to speak before a joint session of Congress to the American people.

Nancy Pelosi has hijacked the federal government; that’s why part of it is closed. She has unilaterally decided that our borders will be open, and now she has undermined this tradition of a president speaking before both houses of Congress.

Nancy Pelosi is the closest thing we have in government to a fascist, to a radical authoritarian. They like to throw that label around when it comes to the president of the United States. The president of the United States has done nothing of that sort. Nancy Pelosi repeatedly conducts herself like a fascist. And now we have a problem -- the speaker of the House is an American fascist.

From the January 16, 2014, edition of Westwood One's The Mark Levin Show:

MARK LEVIN: Here’s what should happen at the State of the Union speech -- since these men and women will not use the Constitution to defend this nation, since they will not use the Constitution to confront a lawless president -- worse yet, since they’re funding his activities with these omnibus bills filled with all kinds of crap.

What the Republicans should do is boycott the State of the Union. They should boycott the State of the Union so half of the House floor, because that’s where they meet, is empty. And they should get together and present their own case on the state of the union and explain in an articulate and concise way what the state of the union is and how the president threatens this republic. They need to do something bold that will get the attention of some of our fellow citizens and which the media, which will attack it, but cannot ignore it.
