President Donald Trump's new budget proposal slashes the anticipated funding for the new Air Force One by almost $200 million, after Trump singled out the project as too expensive and demanded the Air Force and Boeing cut costs or scrap it.The budget request for fiscal year 2018, set for release on Tuesday, will recommend $434 million for the research and development of the new presidential fleet, according to a source who obtained the budget documents.That's a hefty cut from the $626 million in previously projected funding for the fiscal year that begins Oct.
