President Donald Trump has never been shy about sharing his opinion of former President Barack Obama, and this week so far was no exception. After accusing the 44th president of wiretapping Trump Tower over the weekend, Trump took to his Twitter once again Tuesday to criticize Obama for releasing 122 Guantanamo Bay prisoners Trump said were back out on the battlefield.

That insult turned out to be not quite accurate: Obama only released nine of said prisoners from the detention camp. Of the 122 people who gained their freedom, 113 actually left Guantanamo under President George W. Bush, according to an Office of the Director of National Intelligence report.

Nevertheless, the tweet wasn't the first time Trump has attacked his predecessor. From the “birther” movement to Trump’s opinions on Obama’s tense relationship with Russia, check out a list of things the president has said about Obama in the past below.

1. During a March 2011 appearance on "The Laura Ingraham Show:" "He doesn't have a birth certificate, or if he does, there's something on that certificate that is very bad for him. Now, somebody told me — and I have no idea if this is bad for him or not, but perhaps it would be — that where it says 'religion,' it might have 'Muslim.' And if you're a Muslim, you don't change your religion, by the way."

2. During a March 2011 appearance on "Laura Ingraham:" "You know when I started out two weeks ago ... somebody said, 'Do you think he was born in this country?' I said, I can't be 100% sure. Well, let me tell you, after working on it for two weeks I'm a lot less sure than I was two weeks ago.”

3. On Twitter in December 2011: “The habitual vacationer, @BarackObama, is now in Hawaii. This vacation is costing taxpayers $4 million +++ while there is 20% unemployment.”

4. While appearing on “The O’Reilly Factor” back in August 2016: "I think he’s the worst president, maybe, in the history of our country. I think he's been a disaster. He's been weak, he's been ineffective. I believe I know far more about foreign policy than he knows. Look at Ukraine. He talks about Ukraine [and] how tough he is with Russia, in the meantime, they took over Crimea."

5. During a military town hall back in September 2016: "[Putin] has very strong control over a country. Now, it's a very different system, and I don't happen to like the system, but certainly in that system, he's been a leader. Far more than our president has been a leader."

6. On Twitter in November 2014: “Sadly, because president Obama has done such a poor job as president, you won’t see another black president for generations!”

7. While talking on "The Hugh Hewitt Show" show back in August 2016: "No, I meant he's the founder of ISIS. I do. He was the most valuable player. I give him the most valuable player award. I give her, too, by the way, Hillary Clinton."

8. On Twitter in August 2016: “President Obama will go down as perhaps the worst president in the history of the United States!”

9. On Twitter in March 2014: “By Obama mentioning Manhattan yesterday in his response, he has singlehandedly made it target #1. How totally stupid is this guy?”

10. On Twitter in November 2016: "A fantastic day in D.C. Met with President Obama for first time. Really good meeting, great chemistry. Melania liked Mrs. O a lot!"
