Senate Majority Leader Mitch McConnell marked the Supreme Court's historic decision to uphold President Trump's travel ban in his own way.

McConnell's official campaign Twitter account tweeted out a caption-less photo of McConnell with Justice Neil Gorsuch on Tuesday.

McConnell (R-Ky.) blocked former President Barack Obama's Supreme Court pick of U.S. Court of Appeals, Judge Merrick Garland, paving the way for Trump to nominate Gorsuch.

Tuesday's decision was also a reminder of McConnell's past moves that worked in favor of conservatives. In 2016, McConnell moved to block Judge Merrick Garland after he was nominated by Barack Obama to succeed Justice Antonin Scalia after his death.

Tuesday's decision was also expectedly met with criticism from Democrats.

Sen. Bernie Sanders (Vt.) tweeted that the travel ban "was never about keeping America safe."

The controversial ban affects several mostly Muslim countries, and the Trump administration has argued that it was needed for security reasons.

Sen. Lindsey Graham (R-S.C.) tweeted that the ban was "focused no countries that are in true states of disarray."

Gorsuch also was the deciding vote in Wednesday's landmark 5-4 ruling against "fair share" union fees.

As a result of the decision, state government workers cannot be forced to pay fees to support collective bargaining and other union activities.

While the current case applies only to public-sector employees, the political and financial stakes are potentially huge for the broader American labor union movement, which had been sounding the alarm about the legal fight.
