NATO and the Baltic States: Trump White House and Senate Foreign Relations Committee at odds?

I sense a potential area of conflict between the Trump White House and the Senate foreign relations committee.On MSMBC Morning Joe Nov. 15, committee member Sen. Tom Cotton (R-Arkansas) expressed firm support for US support of NATO and for protecting the Baltic States from Russian encroachment. Donald Trump as a candidate had called NATO obsolete, asked why we should go to war of these small countries, demanding that they pay their way (the Baltics are living up to their financial obligations while others in NATO are not) , and seeming to excuse Russia's sly takeover of eastern Ukraine, parts of Georgia, and the Crimea, while his campaign was communicating with Putin.. The Russians now boast they indeed were actively influencing the election.
