(Reuters) - U.S. President Donald Trump has long targeted big tech companies like Amazon, Google, Facebook and Twitter in his social media comments, accusing them of working against him and his administration.

The U.S. Justice Department on Tuesday launched a broad investigation of major digital technology companies into whether they engage in anti-competitive practices.

Here are some of Trump’s past comments on the companies:

AMAZON.COM INC:

July 22: The Amazon Washington Post front page story yesterday was total Fake News. They said “Advisors wrote new talking points and handed him reams of opposition research on the four Congresswomen.” Now really, does that sound like me?

June 16: A poll should be done on which is the more dishonest and deceitful newspaper, the Failing New York Times or the Amazon (lobbyist) Washington Post! They are both a disgrace to our Country, the Enemy of the People.

March 4: The American Media has changed forever. News organizations that seemed like a big deal are now extinct. Those that remain have now degraded themselves beyond recognition.

Jan. 13: So sorry to hear the news about Jeff Bozo being taken down by a competitor whose reporting, I understand, is far more accurate than the reporting in his lobbyist newspaper, the Amazon Washington Post. Hopefully the paper will soon be placed in better & more responsible hands!

Jan. 12, 2019: I just watched a Fake reporter from the Amazon Washington Post say the White House is “chaotic, there does not seem to be a strategy for this Shutdown. There is no plan.” The Fakes always like talking Chaos, there is NONE.

July 23, 2018: The Amazon Washington Post has gone crazy against me ever since they lost the Internet Tax Case in the U.S. Supreme Court two months ago. Next up is the U.S. Post Office which they use, at a fraction of real cost, as their “delivery boy” for a BIG percentage of their packages.

March 31: It is reported that the U.S. Post Office will lose $1.50 on average for each package it delivers for Amazon. That amounts to Billions of Dollars. This Post Office scam must stop. Amazon must pay real costs (and taxes) now!

March 29: I have stated my concerns with Amazon long before the Election. Unlike others, they pay little or no taxes to state & local governments, use our Postal System as their Delivery Boy (causing tremendous loss to the U.S.), and are putting many thousands of retailers out of business!

ALPHABET INC

July 16: “Billionaire Tech Investor Peter Thiel believes Google should be investigated for treason. He accuses Google of working with the Chinese Government.” @foxandfriends A great and brilliant guy who knows this subject better than anyone! The Trump Administration will take a look!

March 27: Just met with @SundarPichai, President of @Google, who is obviously doing quite well. He stated strongly that he is totally committed to the U.S. Military, not the Chinese Military ... Also discussed political fairness and various things that @Google can do for our Country. Meeting ended very well!

March 16, 2019: Google is helping China and their military, but not the U.S. Terrible! The good news is that they helped Crooked Hillary Clinton, and not Trump ... and how did that turn out?

Nov. 15, 2018: The only “Collusion” is that of the Democrats with Russia and many others. Why didn’t the FBI take the Server from the DNC? They still don’t have it. Check out how biased Facebook, Google and Twitter are in favor of the Democrats. That’s the real Collusion!

Aug. 28: Google search results for “Trump News” shows only the viewing/reporting of Fake New Media. In other words, they have it RIGGED, for me & others, so that almost all stories & news is BAD. Fake CNN is prominent. Republican/Conservative & Fair Media is shut out. Illegal? 96% of...

- ....results on “Trump News” are from National Left-Wing Media, very dangerous. Google & others are suppressing voices of Conservatives and hiding information and news that is good. They are controlling what we can & cannot see. This is a very serious situation-will be addressed!

July 19: I told you so! The European Union just slapped a Five Billion Dollar fine on one of our great companies, Google. They truly have taken advantage of the U.S., but not for long!

FACEBOOOK INCJuly 11: The White House will be hosting a very big and very important Social Media Summit today. Would I have become President without Social Media? Yes (probably)!

- Facebook Libra’s “virtual currency” will have little standing or dependability. If Facebook and other companies want to become a bank, they must seek a new Banking Charter and become subject to all Banking Regulations, just like other Banks

- We have only one real currency in the USA, and it is stronger than ever, both dependable and reliable. It is by far the most dominant currency anywhere in the World, and it will always stay that way. It is called the United States Dollar!

May 3, 2019: - I am continuing to monitor the censorship of AMERICAN CITIZENS on social media platforms. This is the United States of America — and we have what’s known as FREEDOM OF SPEECH! We are monitoring and watching, closely!!

- It’s getting worse and worse for Conservatives on social media!

Oct. 21, 2018: Facebook has just stated that they are setting up a system to “purge” themselves of Fake News. Does that mean CNN will finally be put out of business?

APPLE INC

March 11, 2019: At a recent round table meeting of business executives, & long after formally introducing Tim Cook of Apple, I quickly referred to Tim + Apple as Tim/Apple as an easy way to save time & words. The Fake News was disparagingly all over this, & it became yet another bad Trump story!Dec. 14, 2018: Thank you to @tim_cook for agreeing to expand operations in the U.S. and thereby creating thousands of jobs!

Sept. 8: Apple prices may increase because of the massive Tariffs we may be imposing on China - but there is an easy solution where there would be ZERO tax, and indeed a tax incentive. Make your products in the United States instead of China. Start building new plants now. Exciting! #MAGA

Aug. 10: Had a very good phone call with @EmmanuelMacron, President of France. Discussed various subjects, in particular Security and Trade. Many other calls and conversations today. Looking forward to dinner tonight with Tim Cook of Apple. He is investing big dollars in U.S.A.

April 25: Looking forward to my meeting with Tim Cook of Apple. We will be talking about many things, including how the U.S. has been treated unfairly for many years, by many countries, on trade.

TWITTER INC

June 9: Twitter should let the banned Conservative Voices back onto their platform, without restriction. It’s called Freedom of Speech, remember. You are making a Giant Mistake!

April 23: “The best thing ever to happen to Twitter is Donald Trump.” @MariaBartiromo So true, but they don’t treat me well as a Republican. Very discriminatory, hard for people to sign on. Constantly taking people off list. Big complaints from many people. Different names-over 100 M.....

...But should be much higher than that if Twitter wasn’t playing their political games. No wonder Congress wants to get involved - and they should. Must be more, and fairer, companies to get out the WORD!

April 23: Great meeting this afternoon at the @WhiteHouse with @Jack from @Twitter. Lots of subjects discussed regarding their platform, and the world of social media in general. Look forward to keeping an open dialogue!

March 19, 2019: Facebook, Google and Twitter, not to mention the Corrupt Media, are sooo on the side of the Radical Left Democrats. But fear not, we will win anyway, just like we did before! #MAGA

Dec. 18, 2018: Facebook, Twitter and Google are so biased toward the Dems it is ridiculous! Twitter, in fact, has made it much more difficult for people to join @realDonaldTrump. They have removed many names & greatly slowed the level and speed of increase. They have acknowledged-done NOTHING!

Oct. 26: Twitter has removed many people from my account and, more importantly, they have seemingly done something that makes it much harder to join - they have stifled growth to a point where it is obvious to all. A few weeks ago it was a Rocket Ship, now it is a Blimp! Total Bias?

Aug. 24: Social Media Giants are silencing millions of people. Can’t do this even if it means we must continue to hear Fake News like CNN, whose ratings have suffered gravely. People have to figure out what is real, and what is not, without censorship!

July 26: Twitter “SHADOW BANNING” prominent Republicans. Not good. We will look into this discriminatory and illegal practice at once! Many complaints.
