Congress approved nearly $72.3 million to build a new pier at the Naval Submarine Base in Groton, but the money may be snatched away to help build President Donald Trump’s wall along the Rio Grande. But because Congress only approved about $1.4 billion for the border wall project, Trump is preparing to divert $7.2 billion in Pentagon funding for construction of the barrier this year. The diversion of Pentagon money has angered Democrats and unsettled a number of Republicans who have important construction projects in their districts and states. There’s a concern the maintenance of military facilities is falling behind. Military construction projects currently have a $116 billion backlog.
