The Republicans don't want Donald Trump to define the Republican Party agenda. They are very loyal. They owe a lot to their donors. The donors hate Trump. The Chamber of Commerce hates Trump. All of these people that the Republicans think they can't get elected without don't like Trump. So it has been a stonewall. This behavior by the House and Senate Republican leadership isn't anything new. All you had to do was to listen what they were saying during the campaign.
