President Donald Trump turned down an invite to the Washington Nationals opening day game Monday in Washington, D.C., but his absence did not mean his name would stay out of the stadium. A large “Impeach Trump” sign was hung from the observation deck above the first base side by protesters, soon after the home team ended their face off with the Miami Marlins with a 4-2 win.

As a tradition that began with former President William H. Taft, the president in office is invited to throw the first ceremonial pitch as the season opens at Nationals Park. Trump, however, did not make an appearance.

Trump is the least popular new president with just about 40 percent people supporting his work during his first two months in office, according to a Gallup poll to gauge approval ratings. Almost 54 percent of all people polled disapproved of Trump and his policies.

Gallup ratings usually show new presidents enjoying a “honeymoon” phase of good approval ratings during their first few months in office, but it looks like Trump is breaking the trend with his consistently low approval ratings. Usually, the honeymoon phase is followed by decreasing popularity in most cases.

Trump is also facing an increased risk of impeachment over the possibility that the president or his associates may have colluded with Russia to influence the 2016 presidential election, which saw Trump defeat Democratic candidate Hillary Clinton to take office, a Fox News analyst said in an opinion piece. A Congressional investigation is being conducted into his aides’ alleged ties to Russia.

“It is no liberal fantasy to say the odds of a Trump resignation or impeachment before 2020 are looking better by the day,” Juan Williams wrote in an article published by the Hill.
