CNN’s Jake Tapper on Sunday got into a heated exchange with Donald Trump’s campaign chairman, Paul Manafort, after Manafort continued to criticize the media for not focusing on the Republican presidential nominee’s message.

{mosads}In an interview on CNN’s “State of the Union,” Manafort said the media had used Democratic presidential nominee Hillary Clinton’s campaign narrative and gone on the attack against Trump.

Manafort said Trump had a “very substantive” week, noting the GOP nominee visited a number of battleground states. He continued to tout the progress the Trump campaign has made. He said Trump’s campaign is organized and moving forward as well, contrary to media reports.

Tapper then pointed to Trump’s Second Amendment comments, in which the nominee appeared to joke about gun owners taking action against Clinton if she were to win the White House. Tapper pushed back against Trump’s explanation of the comments, saying it wasn’t just reporters and the media who interpreted his comments in that way.

But Manafort blamed the media for the controversy and criticized news outlets for not more thoroughly covering the allegations against Clinton.

“As a factual matter, on Monday, my show covered Mr. Trump’s speech, OK? We did. We covered Mr. Trump’s speech. … And we did cover those Hillary Clinton emails,” Tapper said.

“These things, just because you say them, they’re not true. We have been covering the substance. We have been covering the things that are bad to Hillary Clinton.”

Manafort continued to argue, saying the media should have had a serious discussion about the candidate’s economic proposals.

“And Mr. Trump bears no responsibility for his campaign being off-message? His comments about the Second Amendment had nothing to do with why we weren’t covering the economic message?” Tapper asked.

“His point about the Second Amendment was that people who cared about the Second Amendment should be concerned about Hillary Clinton’s candidacy,” Manafort said, “and that those who are concerned probably would take up the cause” to unite politically against her.
