Source: Public Should Be Able To See Democrats' Countermemo, Rep. Byrne Says BYRNE: Well, the only reason - others have forced us to live on a short-term resolution cycle is that we can't get an agreement with the Democrats on those parts of the government because they're holding those hostage to try to get an immigration deal. We've got an agreement on the defense topline. We put in the National Defense Authorization Act that passed both houses by huge bipartisan majorities. == Hi everyone! How should I understand "topline"? Thanks in advance.
