Republican White House hopeful Donald Trump on Tuesday promoted his new book, "Crippled America: How to Make America Great Again," at a book signing in New York, drawing hundreds of supporters to the city's Trump Tower.

In the 169-page read, which The New York Times dubbed a "slender campaign manifesto," Trump argues for higher taxes on financial managers, the repeal of President Barack Obama's signature healthcare legislation, and making concealed carry gun permits valid in every state, among other things.

In the book, Trump jumps from topic to topic at "breakneck" speed and tackles topics loosely linked to the candidate's own life story, the Times critic noted. For inspiration, the tycoon turns to the likes of Teddy Roosevelt and Mike Tyson, both of whom he quotes in his book, the newspaper added.

The book-signing event in New York, nevertheless, drew hundreds of admirers, along with scores of reporters and bloggers covering the event, Fortune noted. Trump used the occasion to underline the core themes of his presidential bid.

"Look at the state of the world right now. It's a terrible mess, and that's putting it mildly," he said in a statement with an advance copy of his book. "It's time to bring America back to its rightful owners -- the American people."

One Trump backer, meanwhile, used his encounter with the candidate to offer some campaign advice, The New York Times noted.

"Bernie Sanders -- what do you think?" Trump asked Vermont resident Kevin Ryan. The fan warned the former "Apprentice" star not to let his guard down if he were to win the Republican nomination and face the Green Mountain State senator in the general election.

"Crippled America" is published by Simon & Schuster, and the list price for the hardcover clocks in at $25. The work is also available as an e-book, which retails for $12.99.

But "accuracy is not a strong feature of this book," not even when it comes to Trump's biographical details, the Times noted. The critic added that many of the points made in "Crippled America" are not particularly new, either, but already appear in some of the tycoon's earlier works.
