Trump says Fed renovations issue might be fireable for Powell

• While the central bank chair doesn't set rates alone, Trump has been increasingly fixated on Powell himself as the reason rates aren't as much as 3 percentage points lower.

Catch up quick: The Office of Management and Budget last week sent Powell a letter demanding answers to a series of questions about overruns and changes in the $2.5 billion project.

• The Fed has asked its inspector general to look into the details.
• Top Trump adviser Kevin Hassett suggested last weekend that Trump could potentially fire Powell over the issue.

What they're saying: Trump, speaking with reporters at an airport Tuesday, was asked if the renovation issue was a fireable offense.

• "I think it sort of is," Trump said.
• Trump, hurling a series of personal insults Powell's way, also suggested there were problems with his sworn testimony to Congress about the building matter.

What to watch: Whether the administration actually acts or not.

• Powell's responses to the OMB letter are due by the end of this week.
