HARRISBURG - Democrats worked to apply pressure Monday on Republican U.S. Sen. Pat Toomey, trying to tie him to Donald Trump and accusing him of obstructionism in the battle over filling the Supreme Court vacancy.

Meanwhile, Toomey can expect demonstrators to appear at his public events and offices around Pennsylvania in the next two weeks while the Senate is in recess, urging him to consider President Barack Obama's high court nominee.One of Toomey's potential Democratic opponents in the fall election, Katie McGinty, used the term "the Trump-Toomey team" during a Pennsylvania Press Club appearance Monday in which she hardly mentioned her opponents in a four-way primary race."A Supreme Court hostile to the policies that would help the middle class is the last thing struggling families need, but that's what we are destined to get if we end up with a Trump-Toomey ticket," McGinty told the luncheon.Toomey, she said, has not denounced Trump over the Republican front-runner's "hateful" attacks, and "in Pat Toomey's world, President Trump picks a Supreme Court justice and Sen. Toomey votes 'yes.' "Toomey's campaign shot back at McGinty, saying she "has run out of things to say about her own record, so she's throwing mud at Pat Toomey."Also running for the Democratic nomination is Braddock Mayor John Fetterman, former U.S. Rep. Joe Sestak, and Joe Vodvarka, a semiretired owner of a spring manufacturing shop outside Pittsburgh.The primary election is April 26.Toomey, who is running for a second six-year term, has maintained that he wants to wait for the next president to take office before the Senate considers a high court nominee. Toomey has said he will support the Republican presidential nominee, even if it is Trump.Still, Toomey has been critical of Trump's pledge to bar Muslims from entering the United States, his equivocating over former Ku Klux Klan leader David Duke's support and his retweeting a quote attributed to Benito Mussolini, the 20th century fascist dictator of Italy.In statements through his campaign's Twitter account, Toomey said on Dec. 8, "Trump is wrong. We should not have a religious test for admission to U.S. We should have a security test, and it should be bulletproof." On Feb. 28, he wrote on Twitter, "Trump comments on KKK/Mussolini appalling."Toomey had endorsed Florida Sen. Marco Rubio for president, but Rubio dropped out of the primary race.On Monday, Pat Millham of the liberal group Americans United for Change, said he expects demonstrations at every Toomey office and public event in Pennsylvania in the coming days.Small groups of demonstrators greeted Toomey in State College during a private event Monday morning and later waved signs outside the 12-story federal building in downtown Harrisburg where Toomey has a district office.One of the Harrisburg demonstrators, Jason Arnold, said he is not adamant that the Senate confirm Obama's nominee, Merrick Garland. But Arnold, 43, said he does want to see the process go forward."That's actually their job," said Arnold, a two-time Obama supporter who plans to vote for Vermont Sen. Bernie Sanders in the Democratic primary. "Their job isn't, 'I'm going to sit on my hands and shut down government.' "
