HA answered my own question; if anyone is interested this is article gives a succinct and easily understandable explanation.
"The veto occurs when a President objects to a bill or resolution. The President usually sends the bill back to Congress with a message explaining his objections; this is known as a direct veto. If the President withholds his signature during the 10-day review period allowed by the Constitution and Congress adjourns during that period, it is considered a “pocket veto” and the bill doesn’t become a law. The last pocket veto used by President Bill Clinton in December 2000."

Also:
"Once a bill has been passed by both Houses, it is sent to the President. The President then has ten days to consider the bill. If he doesn’t do anything, it automatically becomes a law. If he approves of the bill, he may sign it, and it becomes a law. If he disapproves of the law, he can send it back to Congress with his objections. This is known as a veto. The bill then can only become law if both Houses of Congress override the veto.This can only be accomplished by a 2/3 majority vote in both Houses. Obviously this is not an easy task – of the thousands of vetoes issued by presidents, only a small percentage has been overridden"

Overriding a presidential veto requires a two-thirds majority in both the House and the Senate, as specified in Article 1, Section 7. Given the expected vote margin in the Senate, it is unlikely Congress will override the expected President Trump veto, so the veto will be sustained.
