Four different cabinet secretaries will appear before defense-themed committees on Capitol Hill this week as lawmakers continue their work dissecting President Donald Trump’s fiscal 2020 budget proposal.

The biggest headlines for the defense community will likely come from acting Defense Secretary Patrick Shanahan, who is scheduled to testify at the House Armed Services Committee on Tuesday.

Chairman Adam Smith, D-Wash., has already promised intense questioning not only on the budget plan but also the transfer of military construction funds to help pay for Trump’s controversial border wall project.

As Shanahan’s testimony unfolds, VA Secretary Robert Wilkie will appear across the Hill at the Senate Veterans’ Affairs Committee to talk about his priorities for next fiscal year. On Wednesday, Secretary of State Mike Pompeo will lay out the justifications for his budget to a pair of committees.

On Thursday, Energy Secretary Rick Perry will go before the Senate Armed Services Committee to discuss portions of his budget that intersect with military spending.
