【Watch Metamorphoses Online】

There's less than a month to go until election night,Watch Metamorphoses Online and the head of one of the nation's largest TV news networks has admitted that it made a mistake in its coverage.

CNN perhaps aired too much of Republican nominee Donald Trump.

“If we made a mistake, [it was] we shouldn’t have put on as many [Trump] rallies as we did," CNN President Jeff Zucker told Washington Postpolitical correspondent Lois Romano Friday, speaking at an event at Harvard Kennedy School's Institute of Politics.

The reason seemed to be good entertainment.

Zucker did not go so far to say that CNN helped push Trump to secure the nomination, yet he did tout that his network seemed to have a sense early on that Trump was going to be the Republican nominee.

He also noted that Trump made himself much more available than other candidates. Florida Sen. Marco Rubio and former Florida Gov. Jeb Bush both denied CNN interview requests for two months, according to Zucker. Democratic nominee Hillary Clinton was also much less available, he said.

"We wanted access and Donald Trump gave it to us," Zucker said.

Cable news channels have been under particular scrutiny for how much coverage has been dedicated to Trump, particularly the many rallies he has held. One media analysis firm put the value of the overall time dedicated to Trump at around $3 billion.

CNN has also come under fire for employing former Trump campaign manager Corey Lewandowski, who has become one of Trump's most ardent supporters on the channel.

Zucker may have admitted a mistake, but that doesn't mean CNN is about to change.
