President Trump doesn't plan to fill many of the hundreds of appointed political jobs in his administration because he thinks they're unnecessary.

In an interview with Fox News, Trump said he's been hit for not filling about 1,200 administration jobs that require Senate confirmation, but people don't understand that he's not trying to fill many of those jobs.

"A lot of those jobs, I don't want to appoint someone because they're unnecessary to have," Trump said. "In government, we have too many people."

Trump offered that up as an example of why he gave himself a C for messaging during his first month in office. He said his communication strategy could be clearer and he's going to try and change that around with his speech to Congress Tuesday night.

That communication strategy often involves Trump bringing his message directly to the people through his Twitter account. Trump admitted he doesn't often think about some sort of grand plan when he's tweeting, instead shooting off thoughts on whatever's on his mind.

He used his criticism of Arizona Sen. John McCain as an example.

"[There's] no method really, it's not venting either," Trump said. "But, I felt badly when a young man dies and John McCain calls it a failed mission."

"I thought it was inappropriate and I thought it was inappropriate that he goes to foreign soil and criticizes our government," he said. "People have to be careful about that."

Trump said he doesn't plan to stop using Twitter, which has been a mainstay of his brand long before he decided to run for the highest office in the country. At this point, it's his best way to reach supporters without the filter of the media, he said.

When he tweets, it's clear what he means and no one can interpret it otherwise, he said.

"The enemies would like me to stop it," he said. "If I felt the media were honest, most of it or all of it, I wouldn't do it."
