President Trump devoted three speeches to the nation’s ailing roads and bridges — and made misleading attacks on his predecessor’s efforts to fix them during a week his administration had wanted to focus on infrastructure but was derailed by the public testimony of James B. Comey, the former F.B.I. director.

Mr. Trump announced plans to turn over the Federal Aviation Administration’s air traffic control responsibilities to a private nonprofit organization on Monday, a broad push for a $1 trillion infrastructure investment on Wednesday, and the creation of a council to cut red tape on Friday. Here is an assessment.

Mr. Trump exaggerated when he said the Obama administration’s project to upgrade air traffic control ‘totally failed.’

NextGen, the F.A.A.’s project to modernize its air traffic control system that will shift all aircraft navigation to GPS from radar, did receive most of its funding under President Barack Obama, but the project itself preceded him. Congress approved it in 2003, and the Department of Transportation under President George W. Bush unveiled a comprehensive plan a year later that it aimed to complete by 2025.

The Government Accountability Office has said that some aspects of NextGen will be delayed and cost estimates have been inconsistent but many programs — like GPS navigation — are already working or on time.
