Rep. Frederica Wilson, (D-Fla.), called Donald Trump "a sick man" after he denied having told the widow of a fallen soldier over the phone that "he knew what he signed up for," according to ABC News on Wednesday. Trump, who already is under attack from Senator Ben Sasse, (R-Neb.), for allegedly recanting his Oath of Office, called the widow of Sgt. La David Johnson.

Johnson was killed while on a joint mission with Nigerian soldiers in Niger on October 4. Militants linked to ISIS are the suspected culprits. Wilson, who was riding to the Miami Airport in a car with Johnson's widow, Myeshia Johnson, stated that she was able to hear parts of the conversation between Myeshia Johnson and Trump.

Previous presidents' calls to widows

Trump, who claimed that his predecessors, including Barack Obama, did not call widows of fallen soldiers, prides himself for the calls he has made thus far. Trump stated, "I like to call when it's appropriate when I think I am able to do it," according to ABC News on Wednesday. Trump later recanted his claim that his predecessors did not make similar calls and admitted that he did not know if they had done so.

Trump denies Wilson's claim

Donald Trump denied having told Johnson's widow that Johnson knew that for which he had signed up. Trump stated, "I didn't say what that congresswoman said, and she knows it. I didn't say it at all," according to ABC News on Wednesday. Trump then tweeted that Wilson "fabricated" what he had said and that he "had proof" of such.

No motive to lie

Rep. Wilson was quick to respond to Trump's claim that she fabricated information about the phone call. Wilson stated that she did not want to "politicize" the phone call and that both she and Myeshia Johnson had "no motive" to lie about it. Wilson then stated, "I have no reason to lie on the President of the United States, with a dead soldier in my community," according to ABC News on Wednesday. The Congresswoman also stated she had neither the time nor the motive to lie about the phone call.

Wilson also stated that Trump's remarks were inappropriate for a "grieving widow." Wilson then characterized Trump's remarks to Johnson's widow as "insensitive." Finally, Wilson called Trump "a sick man."

John McCain sounds off

Meanwhile, Arizona GOP Senator John McCain has been very vocal in his criticism [VIDEO] of Donald Trump and Steve Bannon.

In direct reference to Bannon's characterization of America as a land of "blood and soil," McCain reminded Bannon that America is a land of "ideals." McCain also was overtly critical of Trump for the tone and tenor of many of his tweets. McCain also twice voted against Senate bills to "repeal and replace" the Affordable Care Act (ObamaCare).

Johnson's family

Sgt. Johnson left behind his wife Myeshia and two children, a two-year-old son and a six-year-old daughter. Myeshia is expecting a third child in January. A fund has been set up to pay for the education of the three children through GoFundMe website.
