After all those years in real estate and construction, the new president of the United States has a particular penchant for building things, starting with the long-touted border wall with Mexico. Donald Trump has also greenlit the controversial Keystone pipeline project. With Democrats unveiling their own trillion-dollar plan to rebuild infrastructure, could they become Trump's allies against a Republican Party which for decades has been working to cut spending? Is Trump really a Republican?
