President Donald Trump's approval rating plummeted over the weekend to an over two-month low while Russian investigations intensifies and the United States withdrawals from the Paris Agreement.

According to the latest Gallup daily tracking poll, the president's approval among American voters dropped 6 percentage points in just one week, falling from a two-week high of 42 percent to 36 percent over the weekend.

The last time the president's approval rating was this low was back in March when it sank to 35 percent -- the lowest rating of his presidency thus far, according to Gallup.

The administration came under fire from many on the left after Trump announced on Thursday that he would make good on his campaign promise and pull out of the Paris climate change deal former President Barack Obama brokered.

"In order to fulfill my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord," Trump said in a speech announcing the withdrawal at the White House.

"I was elected to represent the citizens of Pittsburgh, not Paris," the president added.

In recent weeks more information emerged on the ongoing investigation into the Trump campaign's relationship with the Kremlin.

Jared Kushner, top advisor to the president and son-in-law, is currently "under FBI scrutiny" over reports he attempted to discuss setting up a backchannel between the Trump team and Russia during a meeting in December.

Other top polls also show a sharp drop in support for the president. After rising to 48 percent approval earlier in the week, the latest Rasmussen poll now shows Trump with just a 44 percent approval rating.

The upcoming week could have a major impact on the president's approval rating moving forward.

Former FBI Director James Comey is scheduled to testify on Thursday before the intelligence committee as part of its own Russia-related investigation and he is expected to be grilled on whether Trump asked him to back off an investigation into alleged ties between the Trump campaign and Russia.
