The Note: Trump’s loyalty test Questions of loyalty – both high and low – haunt the Trump White House.

The TAKE with Rick Klein

“A Higher Loyalty,” James Comey’s new book, has been on sale for 24 hours now.

Questions of loyalty – both high and low – haunt the Trump White House, in this moment where the judicial system is poised to apply the kind of pressure even a president may not be able to resist.

Two allies of President Donald Trump – his attorney Michael Cohen, and his friend Sean Hannity – are now publicly linked to each other and to the president in unclear ways. What they know and what they say could be of more consequence than anything the fired FBI director reveals at this point.

Speaking of loyalty, in Comey’s telling, his relationship with Trump began to unravel with the president’s insistence on it. And an alleged attempt to secure loyalty – by buying silence – is at the heart of the Stormy Daniels matter that’s drawn scrutiny of Cohen.

Trump is known to value loyalty. It may be the quality that he’ll need to fall back on the most to navigate the various legal morasses he now faces.

The RUNDOWN with Emily Goodin

Take me to your leader.

A simple request both parties in Congress are struggling with as Republicans face life without Paul Ryan and Democrats argue among themselves over the role Nancy Pelosi should play.

But the debate is about more than a person, it’s about an identity for the party.

Ryan was asked to be speaker because he was young, energetic, steeped in policy, and a person who could bring all the factions of the GOP caucus together.

Pelosi was the first female speaker, a representative of the liberal elite, and a combination of what the Democratic Party stood for – a disadvantaged group (women) and the progressive wing. Plus she could rule the unruly Democrats with an iron fist.

As both parties debate who will lead them next year, what they’re really debating is an image – conservative or moderate; young or old; establishment or something new – and what’s next for their party as they head into the 2020 election.

The TIP with John Verhovek

It's been just over a month since Democrat Conor Lamb scored an upset victory in the special election for Pennsylvania's 18th Congressional District, and now the GOP is facing a real possibility that another special in the state could take place before November.

Moderate GOP Rep. Charlie Dent's announcement Tuesday that he will resign from Congress "in the coming weeks" presents Gov. Tom Wolf, a Democrat, with the choice to either call a potentially bruising and costly special election sometime this summer or wait until November to see the seat filled.

Pennsylvania state law requires the governor to call a special election at least 60 days after a congressional vacancy officially occurs, meaning that a special election could be called as early as July depending on when Dent decides to step down.

"Once Governor Wolf receives an official resignation notice with an exact date, he will make a formal decision regarding scheduling the date of a special election," a statement released yesterday by the governor's office read.

Complicating matters further is the looming specter of the new congressional maps set to take affect this fall. Under the state Supreme Court's decision, any special election held before November would be held under the old congressional map, and depending on the timing the winner could only end up serving a few months in a district that won't exist after November.
