Trump's Capitol Hill whisperer reveals secrets to president's dealmaking as he heads for exit

EXCLUSIVE: There are few people in the United States who have more significantly shaped the course of American history over the last two years, while remaining as little-known as James Braid.

Millions of Americans across the country may not be familiar with the name, but in Washington, D.C., Braid is hard to miss both literally and figuratively.

At six feet six inches tall, he cast a tall shadow during his days at the White House and on Capitol Hill pushing President Donald Trump’s legislative agenda.

And that shadow has been responsible for helping push numerous legislative successes for Trump over the finish line, from rolling back Biden-era policies to passing Trump’s signature tax policy bill, until Tuesday — which marked Braid’s last day as director of the Office of Legislative Affairs.

The "stock-in-trade" of the job, he told Fox News Digital in a rare interview, "is cautious optimism in the face of all odds." From the outside, being Trump’s whisperer on Capitol Hill does not look like an easy job, particularly when the president is known to personally call out lawmakers who oppose his agenda.

Recently, for example, he publicized the personal phone number of Sen.

Tom Cotton, R-Ark., over his opposition to a bill making Daylight Saving Time permanent .

"There's always a give-and-take in any relationship with a legislator, and sometimes there's a give as a result of, you know, tension," Braid said.

"But you know … one errant Truth [Social post], or one critical Truth, does not a relationship make." But some Republicans’ relationships with the president never seemed to recover, like the case of Sen.

Mitch McConnell , R-Ky., who has no love lost with Trump.

Braid said the key to working with people was always being straightforward about what the White House wants.

"We've been able to be honest brokers and deliver for a lot of these members in different ways," he said.

But Trump’s presence still looms large in Congress whether he’s there in person or not.

A senior administration official familiar with Braid’s work told Fox News Digital that ultimately, "No one speaks for President Trump except for President Trump." The official said Trump is known to be "hands-on at every critical legislative juncture" that pushes his agenda forward.
