William Cohen:

Well, people tend to forget, it was very partisan back in 1974 as well.

Tensions were high. Passions were certainly high as well. There were bomb threats, death threats, a lot going on.

But it wasn't as deep and angry as it is today, and we didn't have social media back then, and we didn't have FOX News back then. I think the combination of FOX and social media has contributed to driving us even further apart, making us angrier than we were even in the past.

So it's a different atmosphere. It's difficult for members of Congress to go against President Trump. He punishes anyone who criticizes him. And even his own intelligence community, his own — our institutions are being politicized on a regular basis, from looking at the intelligence community, looking at the military, looking at the Justice Department.

You can go through all of the institutions, and anyone who disagrees with him is publicly shamed. And so it's more difficult for members today to go against him, and there aren't as many — quote — "moderates" left in the Republican Party to make a difference.
