WASHINGTON - Donald Trump Jr.'s book tour is becoming more of a defense of his father, President Donald Trump, and a prosecution of those who seek to impeach him.
"The reality of the process is totally going to vindicate him," Trump said of his father during an interview Tuesday on CBS This Morning.
While promoting his new book - "Triggered: How the Left Thrives on Hate and Wants to Silence Us" - Trump Jr. also used a number of questions to attack the impeachment drive against the president.
Rep. Adam Schiff, D-Calif., who as chairman of the House Intelligence Committee is leading the impeachment investigation, is "a known hater" who is acting as "judge and jury and executioner," the younger Trump said.
The elder Trump is being investigated for asking the president of Ukraine to investigate U.S. political opponents, including Democratic presidential candidate Joe Biden. Schiff said Trump and allies are also attacking witnesses in an effort to silence them.

In his CBS interview, Trump Jr. said his father did nothing wrong, and is being attacked by members of "the D.C. establishment and the swamp" who want to protect themselves.
"The impeachment process has been going on ... since Nov. 9, 2016," Trump Jr. said, referring to the day after the last presidential election.
There are even people in the White House who are not serving the president's "best interests," Trump Jr. said, but he did not name any.
"There are very few people that he can fully trust," Trump Jr. said.
The younger Trump plans to campaign for his father as he seeks re-election in 2020, and he hasn't ruled out a political race of his own down the line.
"I don't ever rule anything out," he said.

On CBS This Morning, Trump Jr. said his father has shown Republicans that it's okay to "fight back," and he is following suit.
While he would like to see more "normalcy" in political discourse, Trump Jr. said he - and his father - plan to continue fighting impeachment.
For example: When asked to name his favorite Democrat, Trump Jr. responded with the name of one of his father's Republican critics.
"Mitt Romney's my favorite Democrat," Trump Jr. said. "How 'bout that?"
