Special counselor Robert Mueller has reportedly expanded the investigation of Russian collusion to now include obstruction of justice by President Trump. Senior intelligence officials are being interviewed to build a case.

On Wednesday, the Washington Post reported that the investigation has reached a turning point and will no longer just focus on possible collusion between Trump campaign aides and the Kremlin, but it will also investigate any possible financial crimes among Trump associates, officials said.

Although the investigation has not yet been confirmed, President Trump sent a tweet on Thursday which more or less affirmed he is being investigated. In his post, the president called the Russia investigation "phony."

Not only is the president allegedly under new investigation, but based on reports, he may have brought this on himself. 

Mueller's investigation began to focus on Trump after he fired then-FBI Director James Comey in May. Last week, during Comey's testimony, he said he believed he was terminated because of his investigation into Russia's influence on the election.

"I was fired because of the Russia investigation... to change the way the Russia investigation was being conducted," Comey said. "That is a very big deal."

Trump's continuous tweeting about the "phony" Russia investigation has many people wondering why he is still able to control his own Twitter account. 

Additionally, the Senate Judiciary Committee has opened an investigation into Comey's firing. In a letter, Republican Sen. Chuck Grassley of Iowa stated the committee "has an obligation to fully investigate any alleged improper partisan interference in law enforcement investigations."

"It is my view that fully investigating the facts, circumstances, and rationale for Mr. Comey's removal will provide us the opportunity to do that on a cooperative, bipartisan basis," Grassley said.

Although Trump will unlikely be indicted from the current investigation, any findings of wrongdoing could motivate congress to push ahead with the impeachment process.
