Vince Flynn type books
 

Read all of the Vince Flynn books. Any others like that which include cia, fbi, espionage type reading

Jack Reacher books by Lee Child

Look up Rick Murcer (maybe Mercer).

Most of the David Baldacci books. All except the Finisher. Which was also good, just completely different than anything else he did. Also liked the Jack Reacher series.

Brad Meltzer

Brad Thor books, Andrew Petersen (Nathan McBride series)

You could also try Andrew Kaplan and Alex Berenson.

I too have read all of the Vince Flynn books..so sad he is gone. One of my favorite authors in this genre is Daniel Silva. His series on Gabriel Allon is a real treat.
As others have stated, David Balducci is also very good, I've read all of his. I'm currently reading the Jack Reacher series.....I'm interested on what others may suggest here....

Suggest you consider taking a look at Daniel Silva books. His early books had a CIA main character, but then he started the Gabriel Allon series. Allon is a renowned art restorer who is also an assassin for the Israeli Service. Great stories IMO including several involving the Vatican. If you start the series, suggest you read them in chronological order as many characters appear in several books.

David Hagberg - Kirk McGarvey is a CIA operator
Jack Coughlin - Kyle Swanson is a sniper

Kindle authors:

Russell Blake

Steve Konkoly
L.T. Ryan

I just read a great book that reminded me so much of Vince Flynn and it was Agent of Influence: A Thriller by Russell Hamilton. Great read...give it a try.

Nelson DeMille.

David Baldacci, Brad Thor, Michael Connelly, John Lescroat,
Are all very good.

I'm not the OP, but thanks for all of the suggestions
