Input: On Sunday morning   President Trump  expressed frustration that  his  campaign is under investigation over possible ties to Russia's plot to influence the 2016 election but that  his  former opponent Hillary Clinton is not facing the same level of scrutiny.
In four tweets sent over 24 minutes   Trump  wrote: “Never seen such Republican ANGER & UNITY as I have concerning the lack of investigation on Clinton made Fake Dossier (now $12 000 000?)  the Uranium to Russia deal  the 33 000 plus deleted Emails  the Comey fix and so much more. Instead they look at phony  Trump/ Russia  'collusion ' which doesn't exist. The Dems are using this terrible (and bad for our country) Witch Hunt for evil politics  but the R's are now fighting back like never before. There is so much GUILT by Democrats/Clinton  and now the facts are pouring out. DO SOMETHING!”
The history of the dossier  Trump  referenced is a complicated one. During the 2016 Republican primaries  the conservative Washington Free Beacon paid the Washington firm Fusion GPS to investigate  Trump 's background and  eventually  his business ties to Russia  The Washington Post reported Friday. The publication receives financial support from billionaire GOP donor Paul Singer  according to two people familiar with Singer  whose firm did not respond to requests seeking comment.

After the Free Beacon stopped paying Fusion GPS  the research firm offered in April 2016 to continue researching  Trump  for the Clinton campaign and the Democratic National Committee  The Post reported last week. According to that reporting  Fusion GPS then hired Christopher Steele  a former British intelligence officer with ties to the FBI and the U.S. intelligence community  who compiled a 35-page dossier on  Trump . Brian Fallon  a former spokesman for the Clinton campaign  said he learned about Steele and the dossier after the election. People familiar with the matter said the Clinton campaign and the DNC did not direct Steele’s activities.
It's unclear how much the Clinton campaign and DNC paid for the information. The Clinton campaign paid Perkins Coie $5.6 million in legal fees from June 2015 to December 2016  according to campaign finance records cited by The Post  and the DNC paid the firm $3.6 million in “legal and compliance consulting’’ since November 2015 — though it’s impossible to tell from the filings how much of that work was for other legal matters and how much of it related to Fusion GPS. It's unclear how  Trump  arrived at the $12 million figure used in  his  tweets.
[ Trump  and Republicans steer Russia probes in new directions]
When it comes to the “Uranium to Russia deal” that  Trump  referenced in  his  tweet  House and Senate Republican leaders have already announced two investigations into decisions made during the Obama administration  when Clinton was secretary of state  involving a uranium deal that increased Russia’s share of the U.S. nuclear market. At the same time  the House Oversight Committee has launched a probe into the Clinton email investigation that will examine  among other things  why then-FBI Director James B. Comey publicly announced that the bureau was investigating Clinton but then waited months before making a similar announcement about its inquiries into the Trump campaign.

Frustrated with the Russia investigation  Trump demands Democrats and Hillary Clinton face more scrutiny
