According to reports, the White House is getting a new legislative director. Shahira Knight is set to replace Mark Short as the legislative affairs director.

According to The Hill:
 

Shahira Knight, a top White House economic adviser who was instrumental in advancing President Trump’s tax-cut law, will become the president’s next emissary to Capitol Hill, according to three sources familiar with the move.
 
Knight will replace Marc Short, who plans to leave his post as White House legislative affairs director this month. Short has served in the West Wing since Trump’s inauguration.
 
The White House would neither confirm nor deny the move, which was first reported by Politico.  

…

The transition comes at a pivotal time for the White House, which is gearing up for a fierce confirmation battle with Democrats over Trump’s Supreme Court nominee, Brett Kavanaugh. The fight is also expected to have ripple effects on the November midterm elections. 

Until the White House confirms the move, this is purely speculation but it looks like Knight has the credentials to push Trump’s agenda in Congress.
