“Since my resignation as National Security Advisor, the White House has refused to regain access to my personal Twitter account,” Bolton wrote on his Twitter account.

Re: speaking up - since resigning as National Security Advisor, the @WhiteHouse refused to return access to my personal Twitter account. Out of fear of what I may say? To those who speculated I went into hiding, I'm sorry to disappoint!

The ex-adviser said that now he was able to "free" the account and thanked the administration of the social network for returning control of the account to him.

In full disclosure, the @WhiteHouse never returned access to my Twitter account. Thank you to @twitter for standing by their community standards and rightfully returning control of my account.

We have now liberated the Twitter account, previously suppressed unfairly in the aftermath of my resignation as National Security Advisor. More to come .....

Bolton also suggested that the White House might have feared what he might say.

“For those who said that I was hiding - I'm sorry that I disappointed,” he added.
