(CNN)A lawyer for President Donald Trump says a lawsuit is coming against former White House chief strategist Steve Bannon after some brutally critical comments he made in a new book.

Bannon's contributions to the new book, Fire and Fury: Inside the Trump White House, "give rise to numerous legal claims including defamation by libel and slander," said Trump's lawyer Charles Harder.

Whether the President's lawyer follows through or not, just the threat of a lawsuit is a tried-and-true approach Trump has resorted to time and again -- even before he began campaigning.

Below is a list of 10 times Trump has raised the possibility of lawsuits on Twitter. (It doesn't include tweets where he's urged others to file suits):

The New York Times

My lawyers want to sue the failing @nytimes so badly for irresponsible intent. I said no (for now), but they are watching. Really disgusting

If @TedCruz doesn't clean up his act, stop cheating, & doing negative ads, I have standing to sue him for not being a natural born citizen.

Watch Kasich squirm --- if he is not truthful in his negative ads I will sue him just for fun!

Comedian Bill Maher

I don't know whether I will win or lose the @billmaher lawsuit but had an obligation to sue for charity.

.@BillMaher didn't come through with his promised $5 million for charity so today I will sue him.
— Donald J. Trump (@realDonaldTrump) February 4, 2013

I hope @billmaher comes through with his $5 million offer, which I fully accepted, or I will be forced to sue him. All goes to charity!
