The personal account of Rep. Marjorie Taylor Greene was permanently blocked on Sunday because of her repeated violations of the website's policies on COVID-19 misinformation.
A person with the company said in a statement that they will permanently suspend accounts for repeated violations of the policy.
On New Year's Day, the suspension was triggered by a false statement that was made about vaccine deaths being ignored, as well as a false statement that was made about COVID vaccines being dangerous.
She has violated the misinformation policy five times. She lost access to her account for between 12 hours and seven days because of her previous violations.
She had previously made false claims that the vaccines were failing and that COVID was only dangerous to people over the age of 65.
At the time of its suspension, the account had more than 465,000 followers.
The Georgia Republican will still have access to her congressional office's account on the social media site.
The account with more than 387,000 followers could be banned if it is used to violate the rules.
It is normal for US lawmakers to have separate accounts on social media as they are not allowed to raise money or do other campaign activities on their official channels.
In a defiant message posted on Telegram after her suspension, she said, "Twitter is an enemy to America and can't handle the truth."
She is the first member of Congress to have a political account banned from the social networking site.
Donald Trump was banned from the platform due to the risk of further insinuation of violence.
One of the loudest voices in her party is the one who supports Qanon and has been in a racist conspiracy.
She is not the only one.
The Republicans on the House Judiciary Committee deleted their official account after they said booster shots don't work.
According to scientists and medical authorities, COVID vaccines are safe and effective at preventing serious illness, even against more contagious variants, such as Omicron and Delta.
The vaccines have been rigorously tested and are now under the most intense safety monitoring in US history according to the CDC.
More than 3 billion people have received a dose.
