With the FBI busy getting an indictment for Paul Manafort, it's easy to forget that Congress has been holding its own investigation into alleged Russian interference in the 2016 election. The House Intelligence Committee, which has been holding hearings on Russian accounts and ad buys on Facebook, Twitter, and Google, is also interviewing Trump associates to learn about possible collusion. And now they're summoning one of Trump's closest confidants.

According to the Washington Post, Keith Schiller, the president's long-time bodyguard, will be interviewed on Tuesday about a 2013 trip Trump took to Moscow.

Investigators plan to press Schiller about allegations in the 35-page dossier that Russian officials obtained compromising information about Trump’s personal behavior when he visited Moscow for the 2013 Miss Universe pageant, according to people familiar with the investigation.

The Post goes to great lengths to avoid saying "pee tape" throughout their report, but they are in fact referring to the pee tape.

Schiller started directing security for the Trump Organization in 2005 and was briefly director of Oval Office Operations, though he left that position in September out of frustration with John Kelly's restrictions on who could and couldn't see the president. But regardless of his title, Schiller has reportedly been closer to Trump than anyone else outside of the president's immediate family. He was the one who personally delivered the letter firing James Comey and has long been a sounding board for his boss. When Schiller left the White House, sources told Bloomberg that the loss of his "emotional anchor" would be damaging for Trump:

Two people close to Trump said they worry that Schiller’s departure will leave the president and the West Wing off-balance, given the deep relationship the two men share. These people said that Schiller’s exit could put Trump on a collision course with Kelly, who does not understand as well how Trump likes to operate.

Trump is a man who values loyalty above anything else and it seems unlikely that Schiller will intentionally say or do anything to compromise his boss. But beyond the pee tape-specifics, the committee will probably use the interview to learn more about connections between Trump affiliates and anyone associated with the Russian government. And if there's one thing Trump doesn't value in the people around him, it's competence.
