Tried to find what you are talking about. Turned up a lot of political meme's basically saying vote for Trump, because democrats tried blocking the VA Mission Act. Looked up the actual vote counts and it passed successfully with strong bipartisan support in both the house and senate [1]. Are you referring to something else?
If you're referring to Veteran's Choice, while Trump repeatedly and falsely claims to have created it, it was passed into law and signed by Obama in 2014.
