Defense Department officials released their tally on Tuesday after mounting pressure to detail the costs for taxpayers, but they say personnel participation was part of the training budget.

Senate Democrats demanded a government investigation of the unknown costs for President Trump's Fourth of July Lincoln Memorial speech, military flyovers and heightened security.

President Trump's decision to deliver a speech from the Lincoln Memorial and add flyovers, tanks and more fireworks is prompting Democrats to say he's turning the holiday into a campaign rally.

Lawmakers are still waiting to hear the price tag on this year's event. Thursday's celebration is expected to feature military hardware and a speech by President Trump at the Lincoln Memorial.

Rep. Joe Courtney, D-Conn., has attached an amendment to the annual defense policy bill to keep Trump's designs for the next presidential plane within budget.
