As tippy said, that's not really relevant, the fact that someone else also lies doesn't excuse the first liar (particularly when the media's reaction to being called liars has been so hilariously defensive, like that banana ad CNN made, or that time they blackmailed a dude that made a meme making fun of them, or when they awarded themselves person of the year because trump made fun off them).
As for us not having integrity, I'm assuming that's intended to mean something along the lines of an accusation that we're hypocrites because we're focusing on the media and not him. In which case, while it's true we have the media a harder time, they deserve a harder time. Politicians always lie, that's a known fact and everyone expects it. The media is supposed to be a check on them, not a willing ally of one party or another who behaviors barely differently. Pointing out how far they've fallen and how useless they are isn't hypocritical.
