Former Democratic National Committee Chairwoman Donna Brazile said Hillary Clinton's campaign was like a "cult" that became impossible to persuade that it needed to reach out to other states that Donald Trump eventually won.

"It was a cult," she said on MSNBC. "I felt like it was a cult. You could not penetrate them."

Brazile said she has the ability to help candidates reach out to voters, but not if the campaign doesn't agree not spend resources.

"I cannot help a candidate... if I don't have the resources, if I cannot spend the resources that the party is raising," she said.

In her new book, Brazile has criticized the Clinton camp for effectively taking over the DNC before she became the nominee, a move that made it harder for Sen. Bernie Sanders to compete.

But Brazile on Wednesday also faulted the Clinton campaign for failing to work hard enough to win the White House, and dismissed efforts to reach out to much needed Rust Belt states.

"I tried, OK?" she said. "They had a maniacal focus on 270. It was their strategy, it was their plan."

She said she still made efforts to campaign in Colorado, Florida, Pennsylvania, North Carolina, but said she couldn't convince Clinton's team to follow.

Brazile said that when she asked for more resources in those states, she was told "it's OK."

"It was so condescending," she said.
