What's happening in the political world:
Senate committees ask for Comey memos
-- The Senate's Intelligence Committee and Judiciary Committee have both asked for copies of former FBI Director James Comey's memos that detailed his interactions with President Trump.
Sen. Mark Warner, the top Democrat in the Intelligence Committee's Russia probe, also said Comey was invited to testify before the committee. Warner added he was confident Comey would accept the invitation.
"I believe the American people will get a chance to hear from Director Comey shortly," Warner said.
The Senate Judiciary Committee requested that the FBI "provide all memos relating to former FBI Director Comey's interactions with his superiors in both the Trump and Obama administrations," according to a statement.
The committee also asked the White House to "provide records of interactions with former Director Comey, including any audio recordings," an apparent reference to Trump's suggestion that tapes might exist of his conversations with Comey.
Texas congressman calls for Trump impeachment
-- Democratic Rep. Al Green of Texas called for the impeachment of President Donald Trump Wednesday morning, the first member of Congress to officially request leveling charges against the president from the House floor.
"This is about my position. This is about what I believe. And this is where I stand. I will not be moved. The president must be impeached," Green said on the floor. "For those who do not know, impeachment does not mean that the president would be found guilty. It simply means that the House of Representatives will bring charges against the president. It's similar to an indictment but not quite the same thing."
Putin: Russia has transcript of Trump meeting
-- Russian President Vladimir Putin has said his country's officials have a transcript of the talks between President Donald Trump and Russian Foreign Minister Sergey Lavrov.
Putin said the transcript could be provided if the White House agreed.
The Washington Post first reported Trump had shared classified information during a meeting last week at the White House with Lavrov and Russian Ambassador Sergey Kislyak.
Putin denied reports that Trump shared intelligence in the meeting, describing the media reports on the issue as "political Schizophrenia."
Subpoena for Comey memo coming?
-- House Oversight Committee Chairman Jason Chaffetz said Tuesday that if a memo FBI Director James Comey wrote detailing President Trump's request to end an investigation exists, then his committee is willing to issue subpoenas to get it.
. @GOPoversight is going to get the Comey memo, if it exists. I need to see it sooner rather than later. I have my subpoena pen ready.

According to a memo written by Comey detailing his discussion with Trump, the president asked the now-former FBI director to end his investigation of Flynn one day after he fired Flynn as national security adviser. The New York Times first reported the memo Tuesday and a source familiar with the matter confirmed the contents of the memo to CNN.
How did we get here?
-- The New York Times reported that former FBI Director James Comey had written a memo accusing Donald Trump of asking Comey to end an ongoing investigation into Michael Flynn, Trump's former National Security Adviser.
How the U.S. impeachment process works
-- The word "impeachment" has been thrown around since President Trump won the election.
It's important to note impeachment is the process, not the outcome.
Two American presidents have been impeached by the House of Representatives -- Andrew Johnson (1868) and Bill Clinton (1999) -- but both were acquitted by the Senate.
Richard Nixon resigned from office before being impeached.
McMaster denies Trump shared classified info
-- During a press briefing at the White House Tuesday, National Security Adviser H.R. McMaster told reporters the president did nothing wrong during his meeting with Russian officials last week.
"... I wanted to make clear to everybody that the president in no way compromised any sources or methods in the course of this conversation," said McMaster.
The Washington Post first reported Trump shared intelligence on ISIS with the Russian ambassador and the foreign minister. Trump himself confirmed on Twitter that he shared "facts," but did so for "humanitarian reasons."
